Ciné-"Kodak" Model BB Junior

Ciné-Kodak Model BB Junior with f1.9 lens
Before Kodak introduced the 16mm film format in 1923, there had been a number of other attempts to use smaller-gauge formats–for reasons of economy–to create an amateur market for moving pictures, but with Kodak's weight behind it, 16mm film was widely adopted and has persisted, in all its iterations, for a century (and, just like 35mm, beginning as a movie film format, it was also then recognised for its size, convenience and availability, and used for still cameras). Kodak's new amateur format was dependent on two essential innovations, aside from its smaller gauge: the cellulose acetate base–otherwise known as safety film (a phrase that persisted for decades, imprinted on film rebates), at the time when flammable 35mm nitrate film was the norm. Among the short-lived small-gauge formats prior to 16mm, 35mm film had been used, split in half to make 17.5mm film, with some systems using the existing perforations on one side, but one can imagine that Kodak deliberately chose the 16mm width with much smaller perforations–on both sides–so as to prevent any simple attempt to use cut-down nitrate stock. The other innovation was reversal processing, meaning that, instead of processing the film to a negative and then needing to make a separate positive print for projection, the same film could be processed–with extra steps–to create a positive, cutting material film costs in half. The reversal process also results in a finer-grained image, in comparison to a negative, beneficial to the smaller frame size in 16mm when compared to 35mm.

The first 16mm Ciné-Kodak camera of 1923 was hand-cranked, as were almost all 35mm cameras at the time: this only changed with the necessity of synchronising sound to image, which happened in the professional field a few short years after the appearance of the first 16mm camera. Constantly turning a handle to advance the film through the camera made hand-holding an impracticality, and a tripod was a necessity (initially, Kodak only sold the Ciné-Kodak as a complete package with tripod, projector, screen and splicer; although aimed at the amateur market, in 1923 this sold for the same price as a Model T Ford). Kodak introduced the Ciné-Kodak Model B two years later (with the first camera being retrospectively renamed the Model A); this featured a wind-up clockwork motor, allowing for the possibility of being used hand-held (the Model A was provided with an optional battery-driven motor, but this was only available for a short time, suggesting that, given the battery technology of the 1920s, this was not a great improvement: battery driven amateur ciné cameras only really dominated with the introduction of Super-8 in the mid-1960s). The design of the camera was also greatly changed to make it much more compact, notably by having the two daylight loading 100ft spools sitting parallel to each other inside the camera body, rather than one above the other as in the original Ciné-Kodak; the viewfinder was also placed atop the front and back of the body, consisting of an reverse-Gallilean type of finder and reciprocal eyepiece which fold down when not in use. It also had a waist level viewfinder not unlike the contemporary Brownie cameras: Kodak's own literature likens using the next version, the Ciné-Kodak Model BB to the simplicity of the Brownie.

The Ciné-Kodak Model BB followed in 1929, a further evolution towards a more compact camera. By keeping the same general layout of the Model B, but using smaller 50ft daylight loading spools (which had been available to the previous two cameras, along with the 100ft spools), the Model BB was also more economical with the space inside the camera body (as Douglas A. Kerr writes, the layout was “tightened up”). The Ciné-Kodak Model BB Junior is a distinct derivation of the Model BB, and dates to 1930. There does not appear to be much on the Model BB Junior specifically online–or at least there appears to be a not uncommon failure to differentiate these two models. Possibly the Model BB Junior originated with Kodak Ltd in the UK (where both my versions of the camera were made) as a simplified production variant of the Model BB. That the BB Junior originates from Kodak Ltd might explain why its name plate has "Kodak" in double-inverted commas, presumably to indicate that the word Kodak is an invented word or trademark, and used like a title, designated as such in British English rather than allowed to go unadorned in American English: the manual uses "Kodak" throughout, with single commas for the manual's title page (the illustration of the footage counter on page 15 does not have "Kodak" but also one cannot see the word 'Junior': this appears to be a photograph of the footage counter on the Model BB not the BB Junior). 

There are two key distinguishing features to separate the Model BB Junior from the BB: it does not have the slow speed button which reduced the frame rate to 8 frames-per-second (found just above the shutter release lever on the side of the body on the BB; it exposes at 16 frames per second, meaning its shutter speed is effectively around 1/30th), nor does it have the waist-level viewfinder. The Model BB Junior was available with either a fixed-focus f3.5 lens, or a focussing 25mm f1.9 Kodak Anastigmat. There were changes during the production runs of all Kodak's early ciné cameras, which can complicate identification: many initially were provided with slower, non-interchangeable fixed-focus lenses, and then gained faster, focussing lenses, and interchangeable ones. When I started researching the Model BB Junior, I did think that having non-interchangeable lenses was one of its distinguishing features, but, subsequently, I've seen examples online which do have interchangeable lenses. The move to faster lenses seems to be driven in part by the introduction of Kodak's first colour film from 1928, Kodacolor (not to be confused with or the later colour negative film of the same name), a lenticular film exposed through its base–like Dufaycolor–and needing a special filter. As a result, it required much more light to register an image; Kodacolor was on the market for a limited period, but one which coincided with advances in Kodak's ciné cameras.

Ciné-Kodak Model BB Junior: cover side with catch
I bought my first BB Junior on something of a whim: having used 2x8mm film for a few projects (and having bought a developing tank for 2x8mm, which would therefore take 16mm-wide film), and also having some 16mm film stock for use in 16mm still cameras, I was looking for a cheap 16mm camera, rather than investing in something more sophisticated which I might not use with any regularity. The Ciné-Kodak Model BB Junior is relatively common, and I bought my first camera for less than £30 online. There are two main considerations against choosing to use the Ciné-Kodak Model BB Junior (or the BB itself) in the present day: firstly, the camera uses double perforated (otherwise known as 2R) film; secondly, the camera takes 50ft daylight loading spools. With regards to the issue of double-perforation, there is some limited availability at the time of writing: Foma makes its R100 film in 16mm double perforation, and a number of double perforated film stocks are available from the Film Photography Project in the US; there is also the possibility of using old double-perforated film stock–which, at the time of writing, I've done exclusively. Less problematic is the 50ft daylight-loading spools: 16mm film hasn't been sold on 50ft daylight loading spools for many years, as far as I am aware (possibly since the 1960s), but although respooling from 100ft lengths (or longer) in the dark may be tedious, it's not difficult. One needs two spools of course, one for supply, and another in the camera for take up. My first camera arrived without any spools, and I spent nearly as much on two 50ft spools as on the camera itself, although, had I waited, no doubt I could have found cheaper spools–or a camera with spools. 50ft spools have a diameter of 7cm, compared to the mode common 9cm 100ft spools.

To load the camera, there is a catch on one side which simply slides from LOCK to OPEN, allowing the cover to then be entirely removed. As already mentioned, the side-by-side spool layout was first established in the Model B: inside the camera body, the take-up spool is uppermost. The supply spool is exactly parallel to this, located behind a hinged door. If there is a spool in the take-up position, this needs to be removed to open the door, which has a small catch at its lower right, seen just below the spool in the image above. 

Detail of pull-down claw held in the open position with the spring clip
Before loading, the manual recommends opening the pull-down claw, which has a metal spring clip to secure it in the open position (it has a semi-circular tab for handling), and opening the sprocket clamps, ensuring that the whole film path is now free for threading the film from the fresh or supply spool, around the sprocket, through the film gate, back around the sprocket again to the empty or take-up spool. The manual also recommends winding the motor a small amount to create tension for the pull down claw when loading. The sprocket clamps have a knurled grip on their pin heads: these pull up, allowing the clamps to pivot away from the sprocket itself, leaving space for the film to be threaded through either side of the sprocket.

With the film path clear for threading, the door to load the new spool of film is opened, revealing the spindle inside. The 50ft spools are designed to fit in one orientation only: one side has a round hole for the top of the spindle, the other square, which fits the bottom of the spindle shaft. This would appear to be designed to prevent an exposed roll of film being accidentally double-exposed: once shot, the film is in the wrong direction on the spool to then be loaded into the supply position. There is also a thin sprung metal finger which is connected to the internal door's opening mechanism: when shut, this rests with some tension on the supply spool and is connected to the footage indicator on top of the camera underneath the handle.

The film peels off the spool 'backwards': it should be emulsion side in on the spool, then passes over the angled roller, emulsion side out for this side to be facing the lens. If the spool is correctly positioned on the spindle, the door will close and latch. The camera is provided with white lines for the correct size of the loops either side on the film gate: the film is threaded through the upper sprocket clamp and then through the film gate. The film gate is sprung against the square aperture behind the lens: the film threads between this and a plate behind, and then loops through the lower sprocket clamp. The upper and lower clamps should be closed in that order, ensuring that the perforations on the film are located on the sprocket teeth, with the right size of loops formed, but sometimes on loading, I've found that this does need adjusting, finding the right pair of perforations on which to close the clamps to get the loops the right size. Once through the film gate and both sides of the sprocket, the camera can be very briefly run and the pull-down claw will automatically disengage from the spring clip; the free end of the film then needs to be threaded through to the slot in the centre of the take-up spool in the direction of the curved arrow printed around the take-up spindle.

Once fully threaded, it's advisable to very briefly run the camera for a second just to make sure the film is running freely from supply to take-up, through both sides of the sprocket and through the film gate. The exposure lever pushes down to run the camera; pushing this further locks it into in the running position. Replacing the cover, there's a shallow semi-circular cut-out for the lens side for correct orientation, and the catch slides back to the Lock position. The cover will only lock if the film spools are properly seated on both spindles and the sprocket clamps properly closed. On both cameras that I currently have, the serial number, located on the camera's winding key, is also written in pencil inside the cover, partially hidden by its internal catch when in the OPEN position.

As described above, the fact that the BB Junior takes double-perforated film is a consideration against using it today: there are other considerations, concerning the ease of use, in choosing such an early 16mm camera. It is entirely manual, without any later innovations–such as a reflex viewfinder for accurate focus and framing, or metering for exposure–as would assist the amateur user. The viewfinder is a relatively simple reverse-Gallilean type, consisting of a small eye piece at the back of the camera and a corresponding viewfinder at the front, both of which fold down to the body when not in use.

The viewfinder has parallax marks for the top of the frame at 6ft and another at 2ft. As the viewfinder is directly above the lens, parallax is only a problem vertically, not horizontally. Focus on the 25mm f1.9 Kodak Anastigmat is manual, estimated, with marks in feet only, around the lens down to a close focus of 2 feet. The 25ft mark is picked out in red as a hyperfocal setting: the manual states that when set at this distance, with an aperture of f5.6 or smaller (the lens stops down to f16), everything from 8 feet to infinity will be in focus.

For exposure, until 1940 Ciné-Kodak cameras were provided with a guide plate matching aperture settings to lighting and subject conditions, which align to a pointer on the aperture ring. When the first Ciné-Kodak appeared, this had a logic to it as there was only one single 16mm film available, so the descriptions of lighting and subject conditions were not complicated by different film speeds; very quickly however, Kodak introduced a Ciné-Kodak Panchromatic film (the original Ciné-Kodak safety film was orthochromatic), then Kodacolor film (soon discontinued), Super-sensitive Pan film, and Kodachrome, all of which required different exposure settings.
 
Ciné-Kodak BB Junior aperture guide plate
At the time the Ciné-Kodak Model BB Junior was introduced, the films available were Ciné-Kodak Panchromatic film, Super-sensitive Panchromatic film, and Kodachrome: the directions on the aperture plate are for the Panchromatic film; the manual advises with Super-sensitive Panchromatic film to use the next smaller aperture for the conditions described, while Kodachrome had its own exposure guide provided with the film. Kodak abandoned the aperture plate guides in 1940, announced in the March-April issue of Cine Kodak News: new cameras had a 'Universal Guide' on the side of the camera, a plate into which the user could insert a card, included with each roll of film, which could then be read against a dial aligning subject conditions to aperture setting. Owners of cameras produced before this point could have one of these new guides fitted, and at the same time the aperture plate would be removed and replaced with a plate usually featuring a name or logotype. Both of my BB Juniors have the original aperture plates however, possibly suggesting that they may not have been used much after this date–or simply that the original owners did not want the cameras altered.

For a first test, I shot a short roll of Eastman 4-X through the camera. Originally 500 ISO in daylight,  the film is more than three decades old as 4-X was discontinued in 1990. The film has lost a lot of sensitivity with age, and there is a lot of base fog, particularly along one edge. I nominally rated the Eastman 4-X film at 25, although I didn't meter for the exposure, which was simply light projected on a wall. This was developed in Ilfotec LC29, diluted 1+19 for 8 minutes at 18ºC. The results were pretty uninstructive, but the camera did appear to work.

Ciné-Kodak Model BB Junior first test
I then shot some double-perforated Kodak Plus-X. As described in 'Workers Not Leaving The Factory (Once More)', when fully wound, the clockwork motor runs for just over 30 seconds, although it does audibly begin to sound as though it is running slow after about 25 seconds, notably with film (when not loaded with film, there's less drag on the mechanism, so it runs more freely). I had planned a film with four uninterrupted shots of 30 seconds each to use a whole 50ft roll. This was filmed on the A104 Woodford New Road, showing the northbound and southbound lanes of the road both north and south of the junction with the A406 North Circular known as the Waterworks roundabout. I framed a narrow band of the road which used to feature a cattle grid, relatively recently removed, but discernible in the concrete edges of the shallow trench which formed the base of the grid. The cattle grids had been necessary due to a herd of cattle which had grazed freely on nearby Wanstead Flats, but also roamed between other grazing spots, sometimes along suburban streets. The cattle were removed around the time that the M11 Link Road was opened in the late 1990s. After filming the four scenes of 30 seconds each, there was still some film left from respooling. When the footage counter reaches the zero mark, the manual instructs the user to run the camera until a circular mark after zero is indicated, as provision for a trailer on the roll of film, ensuring that no footage is spoiled on unloading. Without the need to reload immediately, I could do this in complete darkness and use all the film on the roll, so filmed a few short scenes at the same location. I did try loading the camera in the dark, especially with short lengths of film for testing, but this makes it difficult to achieve the right-sized loops: too small and the loops are too tight, creating a 'jumpy' gate as the film pulls against it; too large, and the film can drag against the interior of the camera body.

Ciné-Kodak Model BB Junior Plus-X test
Before developing this film, I shot a very short test on the same Plus-X stock (from the roll as used on Expired Film Day in 2020, dating to 1992) to check my exposure and developing times were right. This was loaded in the camera in the dark with some difficulties, exposed at 40, and developed in Ilfotec LC29, diluted 1+19 for 5m30s at 20ºC. Although short, this looked good enough to develop the 50ft roll of Plus-X with the same time and dilution. I had this roll of 16mm Plus-X professionally scanned, and when the scan was returned, it was immediately clear that there were problems with focus: in the middle of the frame, focus was clearly off, although towards the edges, the images looked sharp enough.

    

For what I had intended to film, the four framings of the no-longer-extant cattle grid, this wasn't too intrusive, and I imagined if this were even to be shown, that these four scenes could be played on four screens, simultaneously. However, with any more detailed or static scenes, this lack of focus was distracting. One of the curiosities of the design of Kodak's 16mm cameras around this period is their curving film path through the gate–and that this curves away from the lens. With cheap still film cameras, many have a film plane curved towards the lens to make up for distortion inherent in cheap lens designs. In the Ciné-Kodak Model BB Junior, possibly the curve away from the lens may be in part to have a smoother film path from the upper loop to lower loop, but I did wonder if this itself was part of the problem with focus, in particular that the lens-to-film plane distance was just too short in the centre of the frame to achieve infinity focus. I removed the lens to investigate–it comes off fairly easily with undoing the two screws. I had thought that a solution might be to add a shim, fractionally increasing the lens-to-film plane distance, which I did with a thin sheet of metal cut from a drinks can.

Having removed the lens, I could also see that this was very dirty internally, so took this apart, unscrewing the front and rear groups, and cleaning all surfaces before reassembling and fixing the lens back to the camera body.

Ciné-Kodak Anastigmat lens disassembled for cleaning

As can be seen in the image above, the f1.9 Ciné-Kodak Anastigmat lens was provided a lens hood (seen upper right) which slots into the lens housing itself with a pin to orient it correctly (the slot for the pin can be seen inside the lens housing in the image above; with the hood better seen in the image below). This lens hood could be replaced with filters attached to a similar hood, designated by Kodak as 'W' mount, and were also colour-coded with a painted rim: I subsequently acquired a couple of yellow filters, which, naturally enough, have a yellow rim. This came in cases either made from brass or Bakelite. The filters themselves are of the push-fit variety, and simply slip on the inside end of the W-mount hood.

I also cleaned the film gate, which I should have done before first using the camera, with accumulated dust and dirt being visible along the top edge of the frame in the scanned film. There is a long metal post with a slotted head and knurled grip at the top of its shaft which unscrews, allowing the film gate, consisting of the gate itself and back plate which slot together, and then can be taken apart for cleaning. There is an arrangement of holes–three round holes, with two linked–on one edge of the gate which appear to be some form of identifying edge mark: this can be seen very clearly in the full scan Plus-X test below.

Film gate removed for cleaning
I made a couple of further tests once I'd cleaned the gate (which should probably be done after every roll of film as good practice) and replaced the lens, and this was the camera which I used to film 'Workers Not Leaving The Factory (Once More)'. The tests looked promising, although it's hard to know whether adding the shim or cleaning the lens internally had made more difference.

Ciné-Kodak Model BB Junior test after cleaning & shimming lens
After cleaning the lens, replacing it with the shim, and then filming 'Workers Not Leaving The Factory (Once More)', I bought a second Ciné-Kodak Model BB Junior. I had an idea that I could modify the sprocket and pull-down claw in order to use single-perforated 16mm film in the camera, which would be useful in terms of being able to use a wider range of new film stocks; I also thought that it might be possible to modify the film gate to the Ultra-16 format, especially given how the holes on the left hand side show that the image formed by the lens covers a wider frame. I found a Model BB Junior for £5 online: if either of these modifications made the camera unusable, I hadn't wasted much money (this also came with two 50ft spools inside). However, when the second camera arrived, it was in better condition, cosmetically at least, than the first one, so that was earmarked for modifications instead–which I have yet to attempt. The photographs illustrating this post are a mostly of the newer Model BB Junior; the older camera has paint losses, especially on the winding key, as can be seen in a couple of images, but this was the camera used for all the moving images.

The second Model BB Junior is in such good condition despite being around 90 years old (although introduced in 1930, I've found no date for the Model BB Junior's discontinuation) that I imagine it can never have been used that much (or its owner kept incredibly good care of it). As an amateur movie format, 16mm was soon superseded by the more economic 2x8mm, then the easier-to-use Super-8, before home movies became electronic with video cameras in the 1980s. 16mm drifted from being the format for the home or amateur use which Kodak designed it to be, to that favoured for educational, industrial, and experimental or independent avant-garde uses. The Ciné-Kodak Model BB Junior has many reasons to dissuade its use today, as outlined earlier in this post; in addition, it isn't the most ergonomic of cameras to use hand held, essentially a rectangular box with a lens on the front; without access to home-developing, as well as being able to respool 50ft lengths of film, it is generally an impractical camera. However, as with many of the still cameras I've written about–indeed, much of this blog–there's a sense, partly a form of social history, in gaining an understanding of these technologies of image-making through their use–often, importantly, their limitations–which is a connection, historically, to both how and why images look the way they do.

Workers Not Leaving The Factory (Once More)

Two years ago, I made a very short film called 'Workers Not Leaving the Factory'. The rationale for this was to record moving images onto Ilford film of the sites of the Ilford’s Britannia Works factory in the town of the same name, identifying two locations that would have been exits from the site at the time that the Lumière brothers filmed La Sortie de l'Usine Lumière à Lyon, its title variously translated into English as Workers Leaving The Lumière Factory in Lyon, Employees Leaving the Lumière Factory, or Exiting the Factory, the first film to be projected in front of an audience, at the Société d'Encouragement de l'Industrie Nationale, on 22nd March 1895. Last year I had the desire to revisit this, 125 years to the day on which the Lumières’ films were first shown to a paying audience in London, but did not do so due to the pandemic restrictions in force on that date. Instead, I made a rather imperfect contact print of the first film to project it at home, alongside a digital projection from a webcam that provided the nearest possible view to those which I had filmed, a visual representation of how the moving image and its dissemination has fundamentally changed the experience of time and space, echoing Patrick Keiller’s desire to make a film of “distant landscapes […] without leaving home.” This was 'ADDITIONAL POURTRAYALS [sic]', the name derived from a phrase in the original programme for the Lumières’ first exhibition of the cinématographe in England, in which I speculated, that, although La Sortie de l'Usine Lumière à Lyon was not named as one of the films shown, it could have appeared as one of these ‘ADDITIONAL POURTRAYALS’.

ADDITIONAL POURTRAYALS [sic]
The original Lumière programme appears in reproduction in a souvenir booklet produced for an event in 1936 to mark forty years since the first public exhibition of the Lumières' Cinématographe in London at the Polytechnic on Regent Street. As well as recreating the Lumières' original programme of short films in the same institution (which now boasted a School of Kinematography), there was also an exhibition showcasing the history and development of the technology of moving pictures, with a number of manufacturers keen to display the very latest advances. Among these were Ilford and Kodak Ltd: Kodak Ltd had a number of Ciné-Kodak cameras and projectors “Showing how Cine Kodak has advanced since introduction in 1923” with dates: the last camera listed is the “Cine Kodak “BB” Junr. f3/5” from 1930. Subsequent to 'Workers Not Leaving the Factory', I’d acquired a Ciné-Kodak Model BB Junior, but that with the faster f1.9 lens. In the exhibition, Ilford showed Dufaycolor, frame enlargements from 9.5mm Selo film and also the “ILFORD CINE SERVICE. Showing processing and control of 16 mm. and 9.5 mm. Ilford Cine Films”. Ilford stopped manufacturing ciné film many years ago, and when making 'Workers Not Leaving the Factory', specifically to shoot this on an Ilford emulsion, I cut FP4 Plus film down to 16mm, unperforated of course, but was able to use this–not without problems–in a Bolex 8mm camera. 

Ilford Fast Pan 16mm Film
For an Ilford motion picture film stock to use in the Ciné-Kodak BB Junior camera, I’d found a couple of 100ft rolls of 16mm Ilford Fast Pan film. On the labels of both there is a stamp "date of test 6.1.69", meaning that the film would almost certainly have been made at the Britannia Works site in Ilford before production there stopped in the mid-1970s. This is very reminiscent to the Ilford Mark V film I used a few years ago, presumably being an emulsion test; when researching that particular film stock, I found a suggestion that this lead to the fifth iteration of Ilford’s HP film, currently HP5 Plus today. It’s possible then that the Fast Pan film could be a version of the FP emulsion, although in the original FP film, the letters stood for Fine grain Panchromatic.

Roden Street, Ilford
Unable to revisit the Ilford sites in February 2021, enacting 'ADDITIONAL POURTRAYALS [sic]' to mark the date instead, I did then return last year as soon as the general 'stay at home' order was lifted on 29th March. I shot the Ilford Fast Pan film where it was originally manufactured in the Ciné-Kodak BB Junior–and subsequently did not develop the film for several months, until very recently, almost a year since the film was exposed. The Ilford Fast Pan film labels do not specify a film speed, and over fifty years since being made, I supposed that the film would have lost sensitivity regardless. My initial tests showed the film had a lot of fog, and I shot the film at an exposure index of 25. 

The Ciné-Kodak BB Junior takes 50ft daylight loading spools, which equates to around 2 minutes at the camera’s frame rate of 16 frames a second. When I filmed 'Workers Not Leaving the Factory', as the 2x8mm format requires the film to be passed through the camera twice, there was a logic to shooting two separate scenes, between which the film needed to be unloaded from the camera, the spools flipped over and then reloaded to shoot the second side of the film. In doing this, I chose the locations where two entrances to the Britannia Works site had been, having researched the site history in some detail in 2013. The first location was the entrance to Sainsbury's car park on Roden Street, the other a section of brick wall on Riverdene Road, which appears to align with what was once the entrance to an alley that led into Britannia Works. The Ciné-Kodak BB Junior runs for just over 30 seconds with its clockwork motor fully wound, this would determine the duration of each scene: I assumed that I would then get four different shots on the 50ft spool; in the event, there was enough film for five scenes, partly due to unloading the camera after shooting in the dark (the footage indicator on the camera suggests that there’s about five feet of film after the zero mark which would usually be exposed when removing the film from the camera). 

Riverdene Road, Ilford
I filmed the same two locations as in 'Workers Not Leaving the Factory' for the first two shots. The next two sites where those related to 'ADDITIONAL POURTRAYALS [sic]': the CCTV camera which records the scene that I had projected digitally, and then I pointed the BB Junior in the same direction as this CCTV camera, but from the ground level of course. This viewpoint was as close as I could get to the scene of the Britannia Works site remotely: at some point in the evolution of Ilford’s sprawling site, it might have been possible to see part of it from here, namely the skating rink which Ilford rented in the 1930s. Reading accounts of the history of early film in Britain in In the Kingdom of Shadows recently, I couldn't help noticing that the cinema was linked to skating in a couple of accounts, usually in the nature of popular fads or crazes:
“SEVERAL EXPLANATIONS have been given of the bad theatrical business in the provinces, reports of which daily reach the managers most concerned in sending out companies. […] Mr. George Dance, who has as much experience of the business side of the theatre as anyone in England, is inclined to think that the comparative effect of cinematograph shows and skating rinks has been exaggerated.”
The World’s Fair, 30 October 1909

“AT THE PRESENT MOMENT the popularity of picture palaces and the reason for it are directing a good deal of attention to the public mind. But these sudden crazes are not new: 30 years ago it was croquet, 15 years ago it [was] cycling, ten years ago it was roller skating…”

The Times, 9th April 1913

Site of Alfred Harman's house, Cranbrook Road
With the nominally-50ft roll not entirely used up, I went to the site of Alfred Harman’s house on Cranbrook Road, where Harman first coated glass plates in the basement, the very beginnings of what would become Ilford, Limited. When I developed the film, I used the developing times for Ilford FP4 Plus with Adox Adonal, an iteration of Rodinal. The developing tank I have been using for 16mm is really designed for 2x8mm: a normal 2x8mm camera roll is 25ft, but, with enough film for a leader and trailer, usually removed after processing, the actual length is closer to 33ft; this does still mean that a 50ft daylight spool has to be developed in two parts, if not strictly halves. The cut appears part way through the third scene shot, spliced together again after developing. 

Cut between two lengths of the film developed separately
The direction of the film through the camera means that the second half of the film was first to be developed first, for which I used a dilution of 1+50 for 15 minutes; the negative looked dense, so I reduced the time for the second half of the film to 12 minutes, which possibly could have been cut further (subsequently using the Ilford Fast Pan film, I’ve rated it at 40 or 50 rather than 25; in the image above it's just possible to discern that the image is brighter, thus the negative is denser, below the cut.). The nature of the film's age and overexposure and/or overdevelopment is that the images have quite pronounced grain as a result. Having developed the film by hand, the cleanness of the process itself could clearly be improved. In addition, by letting the camera’s motor run down entirely while exposing the film is that the frame rate slows close to the end, before the motor stops, with the result that the exposure time increases, the image getting brighter at the end of each scene. With the methodology determining the location and duration of each shot, anything happening in front of the camera was at the mercy of what Siegfried Kracauer would describe as ‘the contingency of the street’: the entrance to the supermarket car park and the road underneath the A406 flyover inevitably provided movement; the CCTV camera was shot hand-held, and a bird can be discerned flying through the shot at one point; the brick wall on Riverdene Road is only animated by subtle signs of the wind in the netting on the scaffolding which appears in the corner of the frame and the shadows from a tree on the right. Movement is also provided by the lack of stability of the frames and the vibrations the camera itself is subject to as the motor unwinds, rotating the shutter, pulling the film from supply to take up spool inside the camera, the intermittent motion briefly pausing its travel at the film gate for sixteen exposures every second.

'With Workers Not Leaving The Factory', showing the two individual frames next to each other had a logic thanks to the nature of the 2x8mm film format. In 16mm, there was a coherence to keeping the revisited scenes in juxtaposition; with the following shots as an angle-reverse angle pair, this had also had a reason to be placed together after the first two. The fifth shot I discarded.

Eastman Double-X - Part Two

In the three years since my post on Eastman Double-X film, observing interest online, the popularity of this motion picture film stock amongst still photographers has steadily increased. As a motion picture stock Eastman Kodak produce Double-X in 35mm and 16mm in bulk lengths, the minimum length being 100ft/33m in 16mm; since my previous post about Double-X, a number of companies now provide 35mm canisters ready loaded with the films for still photographers (I previously bought a 100ft roll of 35mm to load my own canisters); the film is marketed as CineStill BwXX, Film Photography Project's X2, as Double-X from Camera Film Photo, and Nik & Trick among others. My motivation for revisiting Double-X in this post came about through using the film with a different developer from those I'd used previously - D96. D96 is Kodak's recommended developer for black and white negative motion picture stock - which now comprises of just Double-X; comments on my original blog post recommended that I use D96 after my somewhat ambivalent conclusion to the film from using it in 35mm for the best part of a year. It didn't seem particularly fine-grained for its speed, and the speed itself didn't seem fast enough to make it a good all-round film in comparison with 400 ISO films on one side, or finer grained 100 speed films on the other.

Formulas for making D96 from its raw ingredients are readily available online, and it has also been available as a powder, but recently Bellini have produced a liquid version of D96. Evidently there are many advantages to the convenience of liquid developer, especially as a stock solution; my habitual developers are Rodinal/R09 and Ilfotec LC29, which I have used for a number of years: it makes sense, especially when starting out with developing black and white film, not to change too many variables at any point, one of these obviously being film developer. However, I recently shot two rolls of 2x8mm Double-X (reperforated for the format and repackaged by the Film Photography Project) in a Bolex ciné camera, and, wanting to develop the films myself, it seemed wise to try the manufacturer's recommended developer with the film, especially given the small size of the 8mm frame. The short film below was shot on 2x8mm Double-X and developed in D96; for reasons too complicated to detail here, I pushed the film three stops in development, which does account for the contrast, while the appearance of the grain is mostly down to the degree of enlargement necessary from the tiny 8mm frame.

Having used the D96 for a couple of rolls of 2x8mm Double-X, having a litre of D96, I wanted to test the film in 35mm with the developer and it seemed timely to revisit Double-X for a new blog post. For a first test with 35mm, I shot a roll with in a Canon A-1 SLR for a latitude test, rating the film at successive exposure indexes of 64, 125, 250, 500, 1000, 2000 for two sets of six exposures, as seen in the first and second rows below, and developed the film for 6 minutes in stock D96 at 21ºC.

Comparison with the same film developed in Ilfotec LC29 (above) from my previous tests appears to show greater latitude when developed in D96, although the conditions with the Ilfotec LC29 were higher in contrast; the same film when developed in Ilfotec LC29 looks as though the shadow detail drops away faster. It's also possible that the test film developed in D96 is slightly underdeveloped: Kodak's published time for Double-X is 7 minutes at 21ºC (rather than the more usual 20ºC); my notes indicate I developed the film for just 6 minutes at 21ºC.

Double-X at EI 64 (two stops overexposed)
Double-X at EI 2000 (three stops underexposed)
I was a little surprised at the latitude range which this test demonstrated as evidenced in the two shots from either end of the scale above: scanning the film, I was able to pull out as much detail as possible from the negatives when underexposed. This was easier than the equivalent exposures with Ilfotec LC29. Overexposure did compress the tonal range from mid-tones to highlights, giving the images more of a flat look than the lighting alone. The latitude in this test is no doubt due in part to the diffused, low contrast lighting when I shot the the film to try D96, as well as the developer itself.

When I'd previously used the film, I did try pushing it one, two and three stops, with very uneven results at two and three stops. Published times for Double-X in D96 are very limited, but the Massive Dev Chart and Bellini's own data sheet give a time of 25 minutes at 20ºC when rated at 1600. I shot a roll at 1600 in (mostly) challenging lighting conditions. This test was possibly overdeveloped, using 21ºC for 25 minutes, rather than 20ºC.

Double-X at EI 1600
Most of these shots were taken under artificial light, in a low-lit museum setting, with spot-lit displays creating inherently high contrast subjects, the above image being a good example; the Double-X rated 1600 did give relatively good results in these difficult circumstances. There were only a couple of shots that I took under daylight conditions, and these on a fairly dark day in February, not enough to draw any meaningful conclusions, but the results look good enough, as below; generally, daylight would of course give enough light to rate the film at 250. Although the times for push-processing Double-X in D96 are limited, it would be possible to make reasonable guesses for one and two stops, perhaps around 12 minutes to rate the film at 400 and 18 minutes for 800, although I haven't tested for these times.

Double-X at EI 1600
As well as trying 35mm Double-X with D96, I also wanted to see how it would perform in 16mm for various subminiature cameras, notably the Rollei 16 camera (this has reputedly one of the sharpest lenses on any subminiature camera). The results on this post are scanned from the negatives; printing in the darkroom, it might be possibly to resolve more detail from the 12x17mm negative. The best of the shots from the Rollei 16, such as that below, showed D96 to give fairly fine-grained development: with the negative very nearly a quarter of the size of a standard 35mm frame, at a modest enlargement, the quality does hold up (albeit perhaps suggesting the grain of a faster film, but I think the general point holds true).

As a motion-picture negative developer, fine grain is paramount. Grain is inherent to the film's emulsion, but obviously, the appearance of the grain is affected by a number of factors. D96 contains sodium sulfite, which acts as a solvent (as well as a preservative), softening the look of the grain; equally, some of the fineness of the grain in my results may be in part due to the developer's low contrast, particularly on a micro level, smoothing out the look of the grain. This also makes it a good choice of developer for using Double-X in half-frame cameras, as well as subminiature cameras. I did shoot some Double-X in a couple of half-frame cameras for this post, but, again, under fairly poor lighting conditions, which perhaps didn't provide the best conditions for testing the film.

I had been fairly ambivalent about Eastman Double-X prior to using it with D96: it almost felt like a different film, testing it again with a more sympathetic developer. The grain appears finer, the film does seem to have better latitude, and, on my limited tests, it pushes better, with more consistent results. However, a few further reflections on using D96 might be apposite here. The developers I have mostly used for black and white films - Rodinal and Ilfotec LC29 - I have treated as 'one-shot' developers, Rodinal, which I've generally used as Compard's R09 One Shot clearly being so, but also Ilfotec LC29, which Ilford recommend using as a one-shot developer when diluted 1+29, or indeed for best results. At lower dilutions, 1+9 or 1+19, I've tended to use it for just one session, but have developed a number of rolls of film, one after the other. Using a stock solution such as D96 does provide some consideration, namely around temperature and exhaustion. With a highly concentrated one-shot solution, I get the water to dilute the film developer up to temperature simply by adding hot and cold together until these reach 20ºC, then add the concentrated developer. Even if this is cold, adding one 30th part at 15ºC for example, 12ml to 300ml, will not significantly alter the temperature. With D96, I found warming the bottle of stock solution took more care, especially when using this early in the year, when the stock solution might be at less than 10ºC off the shelf. Plunging this into a jug of water somewhat warmer than 20 or 21ºC to bring it up to a working temperature more quickly often meant it would get too warm, and then would need to cool before use. The other consideration, exhaustion, was more difficult to calculate. I bought my bottle of Bellini D96 from Nik & Trick; on their website, the suggestion is that a litre of D96 will process "about 100ft". Presumably this is 35mm film. I developed two lengths of 25ft 2x8mm film, 16mm wide, which probably equates to 25ft of 35mm; I also shot four rolls of 27-exposure 35mm film, and some 16mm film with both the Rollei 16 and Mamiya 16 subminiature cameras. In addition, I used the D96 for some Plus-X too, and the FP4 Plus that I'd shot in the Bolex. With the FP4 film, I developed half the film and the negatives were very thin. This might be partly due to user error of course - most of the roll of Double-X I shot with the Agat 18K produced thin negatives, but this was one of the first rolls of film I developed in D96. Returning to comments earlier in this post about not changing too many variables, obviously, using several different cameras, with different metering systems or none, and also developing different emulsions with the same stock solution of D96 made it more difficult to see when the developer was beginning to exhaust: the last films I was developing with the D96, I found myself having to double their published times in order to get good results - clearly, accurate record keeping would have helped here. Comments about developer exhaustion notwithstanding, using Eastman Double-X film with D96 has lead me to reappraise this film stock - and understand the enthusiasm that still photographers do have for it.

World Toy Camera Day 2017/Halina 110 Auto-Flip

Halina 110 Auto-Flip with Kodak Photo Instrumentation film
For yesterday's World Toy Camera Day, I chose a Halina 110 Auto-Flip as my camera for the day. After having used a relatively sophisticated 110 format camera recently in the Agfa Optima 6000 Pocket Sensor, it was instructive to compare that camera to what would have been the opposite end of the spectrum in terms of price and quality. Although what precisely defines a 'toy' camera is subjective and debatable, the 110 Auto-Flip has many qualifying characteristics: it is almost entirely constructed from plastic, fixed-focus, and, other than the shutter release and film advance wheel, the only user control that affects results is a sliding switch for the film's ASA setting, which simply changes between two apertures. The camera is also brightly coloured, a sure denotation that it is not to be taken seriously.


Halina 110 Auto-Flip
The camera has a single shutter speed, not marked, but probably around 1/60th. There are two apertures, again not defined; the switch on the top slides a plate with a smaller aperture behind the lens. The larger aperture setting is marked for flash or full sun for 100/200 ASA, and flash or cloudy conditions for 400 ASA; the smaller aperture is marked for full sun at 400 ASA. On the top of the camera is a socket for a flip-flash, with distance settings for the flash printed on the transparent window that also functions as the catch to open the door for the film chamber (distance settings are given as 4-9 feet for 100 ASA, or 5-15 feet for 400 ASA). The flip cover is easily detachable; it pivots to an acute angle in relation to the camera itself and supposedly functions as a handle to steady the camera: although the top of the cover has a ruled, grip-like top, the ergonomics are pretty poor. The camera also has a wrist strap.

The lens would appear to be a simple meniscus type; in a number of the photographs taken with the Auto-Flip, some pincushion distortion is evident, with moderate sharpness in the centre. The apertures are relatively small, perhaps f11 and f16, providing reasonable depth of field to the fixed focus lens. The shutter release button is stiff, depressing it gives quite a hard 'click', which must risk some camera shake. The viewfinder, in an odd design quirk is square, despite the 110 negative format being clearly rectangular. However, with the limitations of the Auto-Flip, the main consideration of the viewfinder is simply to ensure the subject is centred, as no accurate framing is possible. As I shot two cartridges reloaded with 16mm film, rather than new 110 stock, as I've written about before, the lack of preprinted frames on the film allows the whole negative area to be used. With the Auto-Flip, the negative is approximately 23mm wide - much wider than the preprinted frame size of around 17mm. However, the image is severely vignetted on the right hand side, which no doubt would be entirely covered by the 110 preprinted frame.

As with the Agfa Optima 6000, the Auto-Flip relies on an internal pin locating the 110 perforations to reset the shutter when advancing the film; unlike the Optima 6000, the pin connects with every 16mm perforation (as in the image above): instead of shooting one blank frame to advance the reloaded film the correct distance, I found it necessary to release the shutter twice after each shot, covering the lens, and even then, thanks to width of the Auto-Flip frame, the frame edges were still butted against each other, although the vignetting at one side of the frame generally made this less noticeable. I shot almost all the photographs on the wider aperture setting; of the two films I used, I've found that the Kodak Photo Instrumentation film gives the best results at an exposure index of 100; subsequently shooting a cartridge reloaded with Eastman Double-X as it was beginning to get dark meant the conditions mitigated against using the smaller aperture setting. The weather conditions were not ideal yesterday, but the Photo Instrumentation film's latitude helped to compensate for this.

The Halina 110 Auto-Flip is entirely typical of a cheap point-and-shoot snapshot model that would be an archetypal 'first camera' from the late 1970s through to the 1980s (indeed, while I first took photographs with a 126 Instamatic, one of my brothers had a 110 'Pocket Instamatic' very much like the Auto-Flip as his first camera). Cheap to buy and very simple to use, the camera would have produced passable results in good lighting conditions on small-scale photo-lab prints; retrospectively, it's sometimes a wonder that such photos, not very sharp, grainy, often underexposed, from a first camera, didn't put people off photography, but the fact that these cameras were designed to be so easy to use, and, that they did simply produce results, was enough to satisfy the desire to take the photographs in the first place.
