Kentmere Pan 100

Kentmere Pan 100 35mm film

It's become something of a commonplace to describe how the ongoing coronavirus pandemic has altered the perception of time, simultaneously stretching and squashing it, making everything from 'before' feel unusually distant, separated. I wrote a post in November 2019 about Kentmere Pan 400 after its rebranding, with the prominent 'pan' added to the name, and in it I compared this to the Ilford Pan 400 film I'd written about previously (being one of two cheaper Ilford films which had only recently then become more widely available in the UK, while the point of comparison being that the Kentmere films are made by Harman, Ilford's parent company at a similar lower price than Ilford's other films); having heard that these-the Ilford Pan films-were to be discontinued, naturally, I then wanted to write about Kentmere Pan 100 as a logical comparison to Ilford Pan 100 and as a companion to the Kentmere Pan 400 post. I hadn't used the slower Kentmere film as much as the 400 previously, and I began as I would with any other film new to me, by exposing a roll for a latitude test. This was done on the day (check) that my work announced that they were moving from being face to face to online for the forseeable future, a week before the UK government issued its general 'stay at home' order.

Subsequently, I used Kentmere Pan 100 quite a bit over the next year and a half, in early autumn 2020, as the initial restrictions were eased and I went back to working face to face, as part of my plan to use the Olympus Pen EE3 half frame camera for the year leading up to the tenth anniversary of this blog, then at the start of 2021 when restrictions were back and I was recovering from my first Covid infection, taking allowed walks for exercise, and taking a camera with me. I had long planned to write this post after having used the film as much as I had; I had thought I should do so as the second anniversary of the pandemic and my first test of the film came around in March this year, but that came and went. 

Kentmere Pan 100 in medium format

Then, at the start of this month, on December 1st, Ilford announced that the Kentmere films were being produced in medium format, having only been previously available in 35mm. This provided the motivation to finish this post, and to add the medium format results to it, and, although I have so far only shot a single roll in medium format, all the tests made so far on 35mm film obviously are still relevant.

I made the latitude test using the Canon A-1; compared to Ilford Pan 100, Kentmere Pan 100 does appear to show greater latitude, although the test was slightly marred by one set of frames being double exposed somehow. The top row of frames on the contact sheet above were exposed at 12-25-50-100-200-400 and developed in Ilfotec LC29 diluted 1+19 for 7 minutes at 20ºC. The lower three rows were rated at box speed, but with some bracketing. One stop either side of box speed scanned well; at 400, the shadow detail starts to look lacking, while at 25, two stops overexposed, the midtones and highlights start to look less separated, making scanning a little more difficult, but probably still printable with some care. In comparison with Kentmere Pan 400, the 100-speed version has less latitude, which is probably in part a function of its contrast, with higher speed films generally being lower in contrast by their nature.

As part of my usual testing of film stocks, I pushed–and pulled–Kentmere Pan 100. I used the film quite a bit during the winter months of 2020-21, and as a result, pushing the film often made sense in terms of working with available light. My first attempts at pushing one stop to 200 and used Ilfotec LC29, which appeared to provide a little more contrast, although most of the photographs taken on that first pushed film were in autumn sunshine, with bright light but relatively low, against deeper shadows. This did suit some of the subjects, as in the second image below.

The second roll of Kentmere Pan 100 at a rating of 200 was developed in exactly the same way, but using the Voigtländer Vito B, with an older lens from the Canon A-1's standard FD-fit 50mm f1.8 lens gave a different feel to the images. These photographs were taken on a couple of bright days in very early January, with very low sunlight, and it might have been more appropriate to pull the film to lower the contrast for many of these images (the top image being of a lower-contrast subject perhaps demonstrates this), but I'd decided to push the film without considering what the weather conditions might be: the results were not unsympathetic however.

As I used the Kentmere Pan 100 over quite a number of months, as well as the different tests, I also used a few different developers, not with the intention of comparing the results, but more simply being the case that I was using whichever black and white developer I currently had in use. It would have been instructive to have been more programmatic in this regard, but I hadn't thought that my testing of the film would have occurred over quite such a long period of time. Harman's own data sheet for Kentmere Pan 100 does not provide any timings for a two-stop push to 400 (the metal 35mm canister does have a box next to that 100 and 200 to mark an exposure rating, logically for 400), but this would be a good comparison to the Ilford Pan 100 film. For that particular film, I estimated an extended development time using Ilfotec LC29, with what I felt at the time were rather mixed results. I tried a different approach then with semi-stand development. I used R09 One Shot diluted to 1+150 for 3 hours, agitating on each hour interval (a method used previously with Ilford HP5 Plus: the theory behind using such a high dilution of Rodinal is to reduce the contrast that accompanies push-processing; no doubt most of the development has occurred by the one-hour stage, but I wanted to give the shadow areas as much opportunity to develop as possible). I did the same with Kentmere Pan 100.

The results (above) were comparable to the approach with the Ilford Pan 100 film, and there's a smoothness to the grain which suggests this to be sympathetic to rating the film at 400, given all the caveats one would want to make in relation to push processing. However, I've not tried a more conventional development regime for a two-stop push with this film to see what the difference might be against this extended semi-stand development.

There are probably more conditions under which one might push a film, compared to pull-processing, but I did also try this with Kentmere Pan 100. As regards the comments above with the one-stop push with the Vito B camera, the roll which I rated at 50 might have been better with higher contrast subjects–as pulling a film reduces its contrast–most of this roll of the film was shot under overcast conditions in January. I used the Kiev-4 rangefinder for this, and it may be a fortuitous combination of lighting conditions, reduced development, and the lens used (the Helios-103), but the results pulled one stop in Rodinal appeared to me to be both smooth and sharp, and possibly represents an achievable look of Kentmere Pan 100 that, of all the different exposure/development combinations I've tried while testing the film, I liked the most (the real test would be to print in the darkroom of course).

I also used the film with a couple of 35mm half-frame cameras, and the relatively fine grain made the film sympathetic to the smaller frame size, although the film used in the Olympus Pen EE3 coincided with that camera's lens becoming loose and providing slightly-out-of-focus images. This was part of my year-long re-engagement, an ultimately frustrating one, with the Pen EE3, with the Kentmere Pan 100 film being one that I had in my camera through the summer of 2020.

As written about at the start of this post, what made me finally gather all the images together and write this post was the introduction of Kentmere Pan 100 in medium format rollfilm. As with the 35mm version of the film, this is clearly intended to compete with other lower priced films currently available, and no doubt it makes sense for Harman to be part of that market for medium format. Just over a week ago, on the shortest day of the year, I shot a roll of medium format Kentmere Pan 100 with the Voigtländer Bessa rangefinder. If it hadn't been for this particular post, a 400-speed film would have been better for the lighting conditions, as, on an overcast day in the middle of winter, I found I was having to use a slower shutter speed or wider aperture than I might have liked, and was using the camera hand-held too.

However, medium format can be quite forgiving and returning to the film in that new format, the results of which were very promising–the film dried flat, and was easy to scan, and I suspect as a choice of emulsions, I'd be more likely to choose Kentmere Pan 100 in medium format perhaps more so than in 35mm in future. As a lower-priced film stock, Kentmere Pan 100 fits a gap, especially given the current circumstances as I write, but I generally feel it's relatively unremarkable–it doesn't compare to Ilford FP4 Plus or Delta 100 as Harman's similar speed films–but as I've written above in relation to pulling it to a rating of 50 with the Kiev-4, with judicious exposure and development the results can be better than one might expect for a 'budget' black and white film, which makes its introduction into medium format (as with Kentmere Pan 400) all the more welcome.

'After Vermeer'



For many years, it was known that Vermeer's painting Girl Reading a Letter at an Open Window originally had a large painting on its far wall parallel to the picture plane which had been painted over. It was believed that  this had been done during the artist's lifetime, with the inevitable conclusion that this act was by the artist himself; more recent analysis had determined that a layer of dirt underneath the overpainted area must have taken decades to accumulate, and therefore the painting–or the version of it as had become familiar since the mid-nineteenth century ‘rediscovery’ of the artist–did not in fact reflect Vermeer’s intention for the work. The painting, held in the Staatliche Kunstsammlungen, Dresden was painstakingly restored, with the later overpaint removed, revealing a framed picture of Cupid holding up a playing card, which appears in two other works by Vermeer. The radically restored painting was the centrepiece of an exhibition, 'Johannes Vermeer: Vom Innenhalten (On Reflection)', at the Gemäldegalerie Alte Meister, housed in the Dresden Zwinger late last year. 

A couple of years ago I wrote about my interest in the art of Vermeer in two posts, Cameras Obscura and A View of Delft. These were written after a trip to Delft, Amsterdam, and the Hague, and the work which I had made there, referencing the long-speculated upon use of optical technology–the camera obscura–by Vermeer, and by another Delft painter, Carel Fabritius, the evidence of which appears to be present in their paintings to a greater or lesser degree. This ‘pre-history’ of the photographic has long been an interest of mine, in relation to my own paintings and their relationship to photographic source material, and I had, in the past, made work with specific references to the paintings of Vermeer. As part of the Staatliche Kunstsammlungen Dresden’s accompanying programme to 'Johannes Vermeer: Vom Innenhalten', there was a small display in the Zwinger’s Café Algarotti. This showed three photographic works in dialogue with Girl Reading a Letter at an Open Window: Alfred Stieglitz’s Sun Rays—Paula, Berlin (1899), which depicts the photographer’s sister writing a letter by an open window, strikingly illuminated through slatted blinds; Tom Hunter’s Woman reading a Possession Order (1997), more directly referencing Vermeer’s painting; and my own After Vermeer. In the Zwinger’s display, this was a digital print, a composite image constructed from a number of photographs which had originated on film. 

After Vermeer, digital composite

As an artwork in its own right, this particular version of After Vermeer had only ever existed as an image on a website many years ago–it was made as a reference image for a painting, one component among others, a working image for part of a trompe l’oeil painting: the painting as a whole had the conceit that it shows a section of an artist’s studio wall. The photograph was paired with a photocopy of the two-page page spread showing the reproduction of Girl Reading a Letter by an Open Window from Arthur J. Wheelock’s book on Vermeer. In the painting, my version of the Vermeer composition appears as a photograph that the artist is working from to make a painting: in the trompe l’oeil, this image has a grid drawn (painted) onto it for the purpose of transferring the image, usually with an element of scaling up, to this notional painting’s surface.

I had initially planned four trompe l’oeil paintings in the series of the studio wall. The painting with the photocopy of Vermeer’s Girl Reading a Letter at an Open Window was selected for the Royal Academy Summer Exhibition in 2001; a second painting, in the same format, with a photocopy of Edward Hopper’s Automat and my own composition based on it, wasn’t selected. I completed a third painting, with a composition of my own which was a more oblique referencing to one of Artemisia Gentilischi’s paintings of Susanna and the Elders, included within. The fourth painting in the series was started but never finished. All four paintings were designed to join together horizontally, with elements spanning from the edge of one painting to the next (that the compositions are cut off at the edges points to the paintings being ‘about’ or using the approach of trompe l’oeil, rather than being true trompe l’oeil works). I kept the board for the fourth painting for many years afterwards. It had a slight bit of painting of the overlapping newspaper clipping. Eventually this got damaged and the board was cut up to be re-used. 

At the time I made this series, in early 2001, I had no intention of making singular paintings of my own compositions within them which refer to the historical paintings that were their inspiration. This was partly that I (then) had a resistance to making paintings that appeared as if (based on) a single photograph, a resistance I relinquished a year or so later. From the other trompe l’oeil paintings completed in the series I used the digital images of my compositions for two back-lit transparencies mounted on lightboxes which were exhibited a couple of times; my version of Vermeer's Girl Reading a Letter at an Open Window was never made into a lightbox, partly a result of being dissatisfied with the quality of the images, mainly as a result of being made relatively cheaply. I began an etching of the image from the composition based on Edward Hopper’s Automat but this was never finished; the other composition I had made as a postcard before eventually using it, with a number of changes, as the basis for a larger painting.

I returned to the Vermeer composition five years later to make a single painting. This was shown in an exhibition at a gallery specialising in photography and subsequently sold. When I received an email from the Dresden museum, my initial supposition was that they wanted to shown my painting in the accompanying programme; this has had a handful of enquiries in the years since I sold it and is now no longer accessible. However, they were interested in the photograph of After Vermeer, which had never been made into a physical version, only ever existing as a digital image on my website, on a page long since orphaned from the site itself, but still online (for a time, there were in fact two digital versions of the composition on my website, the first with a different position to the model’s head). I didn’t ask how the curator stumbled across this, but was relieved that I could show the photographic After Vermeer: as well as the rather low-resolution jpeg online, I still had the original working Photoshop file on a disk. 

A number of things came together to provoke me to make After Vermeer. The initial spark came from receiving a photograph of Tom Hunter’s picture from a teacher that I was still in touch with. This must have been after Woman reading a Possession Order was exhibited at the National Portrait Gallery, receiving a certain amount of exposure. I happened to be living in the London Borough of Hackney at the time, from the very end of the 1990s into the 2000s and, as a result, many of Tom Hunter's locations became very familiar to me, with just a faint, occasional sense of our paths crossing, with Hunter, no doubt completely unaware, several, many steps ahead. At the time I was still working out what kind of artist I wanted to be, but very quickly painting became predominant, although in 2000 this wasn’t entirely clear, and in recent years photographic processes in their own right have become more important once again. I hadn’t studied painting at degree level, studying printmaking instead; after art college I pursued painting as this seemed the easiest route at the time, something I could do in my rented room with the minimum amount of equipment (and cost), not needing a workshop, making do without a studio.

The architecture of the kitchen of the rented house in which I was living at the time allowed me to create a very similar composition to Hunter’s photograph, with a large window to the left over the sink providing just the right kind of diffused light, similar to Vermeer’s original and Tom Hunter’s version. There was space, under the stairs by the back door, to stand far enough back to take the photographs. I think I had planned to combine a number of photographs together to make the digital image to work from for the painting: this allowed me to select from different shots, and combine these to make something closer to Vermeer’s painting. At the time, I imagined this to be like working with photography as a painter works, but, perhaps, this was more to do with not having the confidence to achieve what I wanted in a single photograph itself (I had been much taken by Jeff Wall’s working processes at the time, with pieces such as The Flooded Grave impressing me, although it’s very clear, practically, as to why that work could not be made as a single photograph). Unable to ignore the fact that this was a kitchen, I chose to depict the mundane action of drying dishes, with the light itself standing in or conferring any sense of a moment of the sublime, a contrast to Tom Hunter’s understated photograph given a sense of affect through its title. I did originally call my work After Tom Hunter After Vermeer.

Returning to the original Photoshop file, I discovered that, on closer inspection, it wasn’t really finished: good enough to paint from, I hadn’t needed to ensure a level of finish as the digital file wasn’t to be the end result, but I was still surprised at the lack of care and attention to its editing. It had been made from scans of photographic prints rather than negatives: at the time, I had no access to negative scanning, nor a darkroom to make my own prints. The photographs were taken on medium format and 35mm negatives (from my Ikoflex twin-lens reflex and a Praktica BCA SLR: the strap for the Praktica can actually be seen in the final image, hanging down from being placed on the stovetop, just visible at the edge of the doorframe), but, working from small lab prints, the difference between the formats was probably negligible. This was still essentially a pre-digital world, photographically at least: the medium format film, Ilford HP5 Plus, was developed at a branch of Jessops that used to be in Moorgate; the 35mm XP2 Super went to Tesco on Bishopsgate, opposite Liverpool Street Station: the supermarket used a Kodak lab, and both were a convenient stop on my way to and from my part-time job on the other side of London Bridge. There was probably no consideration to use colour: black and white has a certain connotation of the ‘photographic’, historically situated of course, and a equivalence to the black and white photocopy from the book on Vermeer (with an incidental association to David Hockney’s approach in Secret Knowledge, reproducing paintings in black and white to emphasise their ‘optical’ look which the photocopy achieves). Opening the .psd file after twenty years, this had been saved with some separate layers (there were six layers, but with layers named Layer 8 and Layer 9, others had clearly been merged at the time), making it a little easier to edit the file to achieve what I hoped to be an acceptable a level of finish, neglected twenty years earlier. The original had been printed at 8x10 inches for the painting, smaller than A4 size; I was fortunate in that the curator found the image file to be sufficient in quality at double the size to include in the accompanying programme. Although I still had the original negatives I had been reluctant to remake the image from scratch–although I might have wanted to–and the re-edited digital file was printed for exhibition. I did scan the negatives later, and found that many of the frames were marred by motion blur or were poorly focused, possibly confirming my instinctive lack of confidence over getting it ‘right’ in a single shot.

The Vermeer exhibition opened around the start of the new academic year; I had hoped to go at the Christmas break (and was also hoping to be able to afford to do so too), which would have been around this time last year, to see the restored Vermeer, and to experience a work of mine on display in Dresden, reflecting on its afterlife as something made many years ago for quite different purposes. The emergence of the Omicron variant of the coronavirus meant that the exhibition shut to the public in November, shortly followed by UK nationals being prevented from travelling to Germany. Although 'Johannes Vermeer: Vom Innenhalten' closed at the start of this year, as scheduled, the accompanying programme display was extended into April 2022. Conditions sufficiently improved for travel into Europe in the spring, and I booked to do so in April, just before the extended display was due to finish.

The day before I left London for Dresden, I discovered that the accompanying exhibition in which my photograph had featured had already been taken down, short of the scheduled close its extended display, to clear the way for the accompanying programme for the next exhibition. This was 'Edward Hopper: Die inner und die äußere Welt (Inner and Outer Worlds)', opening a week after we were due to leave. In the Café Algarotti where the accompanying programme had been, I photographed my hand holding a mobile phone showing an image of this display–the image at the top of this post–no longer there by the time I had travelled to Dresden. The image within the image is too small to see my work, the framed picture on the right-hand side, disappearing behind the glare on the glass from the windows opposite, perhaps appropriate. Vermeer’s Girl Reading a Letter at an Open Window was absent, so I did not get to see the restored painting either; the Gemäldegalerie Alte Meister did have his Procuress on display, an earlier painting, where aspects of Vermeer’s particular stylistic approaches remain yet to be worked through, but the still life element of the painting equals that of many of Vermeer’s paintings in his mature style. The blue-and-white Westerwald stoneware jug is painted in sharp focus, existing in an isolated plane in depth, while the figures appear just out of focus, painted with some passages of incredibly thick paint, with barely any sharp outlines, the edges diffused, suggestive of a shallow depth of field from a camera obscura. The foreground carpet and fur provide a means to push the rest of the composition back away from the picture plane as well as hiding any compositional problems of how to resolve exactly how the figures are spaced around the table that the jug and glass are resting upon.

Recalling the kitchen of twenty years earlier, and making of that picture, the architecture in the apartment where we were staying in Dresden had an incidental affinity to Vermeer’s space: a window at right angles to the  kitchen worktop, admitted perfectly diffused light, picking out a kettle, some bread, with a heavy curtain casting a chair and a table into foreground shadow, coming together in a composition, photographed on colour film this time.

127 Day December 2022

Baby Ikonta with cut-down Rollei Superpan

Despite neglecting this blog for a few months now, I couldn't not observe last week's 127 Day. I used the Baby Ikonta again, but had just a couple of rolls of Kodak High Resolution Aerial Duplicating film cut to 127 size, and a short off-cut from a previously-cut-down roll of Rollei Superpan 200 (when cutting down 120 film to 127, the length of the 120 roll is longer than that needed for 127, meaning that with every cut down roll of 120, there's a remainder of film long enough for 5-6 'half'-frames on the '16-on' format); the image above is from the beginning of the short roll which shows that I hadn't accurately lined up the cut end of the film with the start of the numbers on the backing paper. The frames on the Superpan film were hand-held; the Kodak High Resolution Aerial Duplicating film when used as a negative film has a workable ISO of 2. I took most of these photographs in the Victoria & Albert Museum, without a tripod, placing the camera on any level and stable surface I could find that might provide an interesting viewpoint, mostly parapets and benches. I did take one frame, handheld outside, at (I think) 1/10th at f3.5 (the image of Second World War bomb damage to the museum's exterior; another photograph taken outside with this film was made placing the camera on a brick wall).

On a winter's day, the light levels in the museum are often quite low: exposure times were between 8 seconds and approximately 1 minute. When I developed the film using PQ Universal, it was clear that I could have bracketed more, and, possibly at longer times, the film does exhibit some reciprocity law failure. Scanning the negatives, there was a lot of digital 'spotting' to do: the extremely clear shadow areas show up any specks of dust or dirt incredibly well. The blue-sensitive high-contrast nature of the film also shows how the daylight entering the galleries from skylights caused the floor appearing in some of the frames to appear very bright in comparison to almost everything else in the image, with the exception of some of the plaster casts (such as Michelangelo's David).

There was also a denser band along one side of one roll of this film, which I haven't found the cause of, but this may be fogging due to cutting the film down by hand under safelights in an insufficiently-dark darkroom, with something partially shading the film. I did think that this could be due to not using enough chemistry when developing, but usually this would show up as a pattern with the image of bubbles from the surface of the developer. This line can be seen to the left of the cast of the architectural façade in the image below.

The Kodak High Resolution Aerial Duplicating film may also have benefitted from flashing before exposure to raise the shadow values, perhaps something to remember for January's 127 Day. The Rollei Superpan film was less problematic (despite not being taped at quite the right place to the backing paper), but I did use Kodak HC-110 to develop the film, having previously tested this with Rodinal, and worked out a time/temperature/dilution regime to get the best results for my own approach, which I haven't done with HC-110, merely taking the Massive Dev Chart's single recommendation: 6 minutes at dilution B, 1+31 from concentrate.

Kodalux L lightmeter (second version)

Kodak Kodalux L lightmeter and case

One of the peculiarities of the (admittedly niche) popularity of film photography and the perceived value of older film cameras in recent years (and the attendant high prices of secondhand equipment-especially when certain cameras gain a fashionable cache) is the emergence of a new class of shoe-mounted lightmeters. A decade or so ago, this might have seemed an unlikely proposition, but thanks to new manufacturing techniques, there are now a number of meters, largely deriving their design principles from the Voigtländer VC Meter I and II from the early 2000s.

For many years, I've used a hand-held Weston Master II whenever I've needed a lightmeter, although I do also use the 'sunny 16' rule relatively frequently, especially if I'm just taking snapshots when I'm not too concerned with critical accuracy in exposure. One of the features I've really appreciated about the Weston Master II is how low the ISO settings go, down to 2 ISO, useful for exposing photographic paper for paper negatives, and for the Kodak High Resolution Aerial Duplicating film, which I have been using at 2 ISO. However, when taking photographs in December, I dropped my lightmeter on the stone flags surrounding the Pole Hill obelisk on the day of the winter solstice-and it stopped working (it might simple be that the meter needle is stuck, but I have been wary so far in disassembling the Weston Master).
Kodalux L meter - showing diffuser
Looking for a new lightmeter as a consequence, I did consider the new shoe-mounted meters alluded to earlier, but searching for secondhand lightmeters online, I found the Kodak Kodalux L, and was able to pick one up pretty cheaply, around half the price of the cheaper of the new meters currently available. There are two models of the Kodalux L, with the second model being notably smaller than the first, and this made it the preferable choice.

Being a 1950s meter, the Kodalux L is powered by a selenium cell, covered with a typical honeycomb-glass. As I've written in previous posts, selenium cells do attract some negative opinions expressed online, but in my own personal experience, with numerous cameras (and the Weston Master II), I don't think I've actually encountered a non-working selenium cell, and, in general, they have been accurate enough for my preferred photographic medium, black and white negative film. The main caveat is that in low-enough light levels, selenium cells are simply not sensitive enough, but this would generally mean night photography. In addition, the design of most selenium cell meters would make them incompatible with a zone-exposure approach.
Kodalux L with case
The Kodalux L is a prime example of the precision of German manufacturing before their camera industry was supplanted by Japan: the meter measures slightly under 3cm high, including the shoe fitting, 3cm wide and 3.5cm deep. The meter is largely constructed from metal, with a plastic base, embossed with 'MADE IN GERMANY (WEST)'. My meter came with its dedicated 'ever-ready' case (approximately 4x4x5.5cm, with a couple of loops to fit to a thin strap), which has a accessory shoe fitting for use mounted in the case itself. Equally, it can be used mounted on the accessory or 'cold' shoe on a camera. Although branded Kodak (although the meter itself doesn't have the band name Kodak on it, but the case does), the Kodalux L was manufactured for Kodak by Gossen. The first model Kodalux meter is simply a rebranded Sixti; the second Kodalux appears to be a unique model, similar to the Gossen Sixtino or Pilot meter, but with significant differences. Gossen provided the lightmeters to the Kodak Retina and Retinette: the meter dials on some of these cameras appear almost identical to that of the Kodalux.

Use of the meter is simple: a white meter needle responds to light hitting the cell, and, with the correct ISO set, a milled ring or dial is turned to align a yellow pointer to the needle. One can then read the appropriate aperture/shutter speed combinations around the edge of this ring. Being familiar with manual and mechanical meters, I found it immediately instinctive to use; I did find a scan of the manual, which was useful when it came to calibrating the meter. Setting the meter, there is an inner disc, which turns with a stud, which has a window each side displaying film speed in DIN on one side and ASA (ISO) on the other. The ASA ranges from 5 to 1300, a good top film speed for its time. The ASA settings are picked out in what are largely obsolete numbers, at least at the faster end of the scale 160-320-650-1300, but these are divided with marks at thirds in between, so 400 ISO is one mark above 320 for example. Apertures run from 2 to 22; with shutter speeds from 500 down to 4 whole seconds, with whole seconds subtlety picked out in green. For its size, apertures are given in whole values, no half-settings, but one can extrapolate these. Aligning the yellow pointer to the white needle also gives a light value (LV) number in a window at the top of the disc, running from 2 to 18 in red numbers (this window is wide enough to show three readings, and, although it's easy to add or subtract 1 from the reading, this might possibly give a quick reference for over- and underexposure compensation. The meter also has a diffusing cover for incident reading, which slides from one side like a roll-top desk with a tiny metal catch.

When I first got the Kodalux L, the meter did seem to be a little off in its readings. comparing it to readings from my digital camera and the readings from my Canon A-1. From the manual, there is a description of how to zero the meter. This involves completely covering the selenium cell: if correctly set, the needle should point to a blue dot at the far left of the meter window; if not, there is a small screw in the centre of the back of the meter which can be adjusted using a small screwdriver. There are other blue dots in the window, but the manual states that these are used for setting during assembly and "have no significance on exposure readings." I carefully adjusted the setting screw, and the meter now appears to read close to the other meters I have been comparing it to. I subsequently used the meter for filming 16mm (see 'Homage') and with some medium format, including in Dresden. In use, I usually keep the lightmeter inside its case, using it handheld, but, for the purposes of illustrating this post, I photographed the Kodalux L on the contemporaneous Kodak Retina IIa, an appropriately stylistic match.

Silberra S25 Limited Edition - single roll review

Silberra S25 Limited Edition
Silberra S25 is limited edition black & white photographic film. Extra fine grain, moderate contrast and high resolution of the image are the main typical qualities of S25 film. Initial batch of S25 consists of 400 rolls and, possibly, the overall quantity of the batch will be extended up to 800 rolls.

Silberra S25 perfectly suits architectural and landscape photography; due to its great photographic latitude S25 film shall perform nicely at bright scenes also preserving impressive level of detalisation through shadows without significant loss in highlights.

Silberra S25 has high sensibilization level which makes it possible to use S25 for IR-photography with corresponding IR-filter (we recommend to use filters at wavelength shorter than 725nm for optimal result).

I have previously posted a couple of 'single roll' reviews of film stocks, which came from being gifted some films I might not ordinarily have used, or might not use again, and although I prefer to work with an emulsion for a few rolls at least, to get a feel for how it might respond in different exposure situations and approaches to development, this single roll review came about through realising I might not use another roll of Silberra S25 black and white film. As the description above (from Silberra's website) states, at the lower limit, there may have only been 400 rolls of film made, or 800 in total if production was 'extended'. I wasn't aware of this at the time, if so I might have picked up more than one roll. I believe I picked it up from the Photographer's Gallery shop, before the current pandemic, with the intention of using it to photograph some text, thinking that its 25 ISO speed would mean that the grain would be fine enough for the purpose I had in mind; I didn't use it for that, but took it with me to Dresden in the Spring, and shot it with the Kiev-4 over a couple of days.

Understandably, there's not much on line about Silberra S25, and with just the one roll, I simply rated it at 25 ISO, and didn't really think that much about how I was to use the film. The film cassette is a plastic reusable one, but it is DX coded, and also has check-boxes for exposure at 12, 25, and 50 ISO, indicating that it does have sufficient latitude for this to be worth the manufacturers including on the label. Silberra's webpage has a small development chart, presumably all times listed are for box speed, although this isn't stated. I used Adox Rodinal, and the time/dilution given (at 20ºC) is for 6 minutes at 1+100. This seems a high dilution for 'standard' development, but, again thanks to having just a single roll, I used the published time and dilution. (There is also R09 listed for 30 seconds less than Rodinal, where one might have expected this to be the same: I have used both Foma's version of R09 and Compard's R09, and treated these both as any named version of Rodinal).

When developed, the negatives looked relatively high in contrast, with a clear base and no edge markings whatsoever. The film dried very flat and appeared to show a small amount of 'light-piping': the film base appears to be polyester and not tri-acetate (it doesn't tear and needs cutting). Ideally, I would have made prints in the darkroom from the negatives, but the results on this post are all from scans from a desktop scanner. The scans have almost no discernible grain, and no doubt show up the limitations of the desktop scanner rather than the ultimate resolution of the film itself. I'd shot the film outside, half in bright sunny weather one afternoon, ideal for it relatively slow speed of 25, with the other half shot early on a sunny morning, which was more challenging in terms of exposure, thanks to the low angle of the sunlight creating a very wide range of contrast between brightly lit surfaces and deep shadow with little in-fill from reflected light. Some of these latter frames (as below) struggled to record shadow detail without losing detail in the highlights, which didn't quite match the assertion that "due to its great photographic latitude S25 film shall perform nicely at bright scenes also preserving impressive level of detalisation[sic] through shadows without significant loss in highlights".

It would have been instructive to see how scenes lit with well-diffused light, such as on an overcast day, might have been recorded, but almost every single frame I shot with the film was sunlight and shadows. The nearest equivalent was one photograph of a sign in a gallery window, below, illuminated by light reflecting off the pavement and surrounding buildings, almost certainly the one negative with the narrowest exposure range (this, incidentally, showed that my original intention for the film–photographing text–would have been an entirely appropriate use).

Not having an IR filter I was unable to verify the film's 'high sensibilization level': given the suggestion for the use of an infra-red filter, this must mean extended red sensitivity. For some frames I might have used a light yellow filter, regardless, the tonality of the sky in some frames possibly indicates a more balanced spectral sensitivity than standard panchromatic film. My general impressions are that Silberra S25 has the feel of some kind of technical film–for me, how it handled and how it responded to exposure was very reminiscent Kodak Technical Pan–with both the positives and drawbacks of that discontinued emulsion. Given the very limited production run, it would be interesting, if it was possible to quantify, how many rolls of Silberra S25 are still out there, yet to be exposed: it's still listed on the Photographer's Gallery shop online, but sold out.
