There was another vertical shot of the fairground which I accidentally spoiled the exposed plate by pulling out the wrong darkslide when setting up to shoot a different scene. <br />How stand development works, as I understand it, is that with highly dilute developer (in itself low contrast), as it works on the highlights, the developer's action is restrained by the local build up of exhausted developer, or developer by-products, not dispersed by agitation, in effect keeping the highlights from blocking out, while shadow areas are able to develop to completion. This seems to be quite sympathetic to what might be either an over- or under-exposed latent image, although with the night shots I usually err on possible overexposure to get a usable negative.<br />I've not heard of Barnet Presstopan (I'm guessing a fast panchromatic plate for press work), the only Barnet plates I've used have been line tone plates, hideously fogged: http://www.flickr.com/photos/nicholasmiddleton/8976768992/<br />I did think about illustrating the adaptors; these were made from two pieces of mountcard, one to the size of 4x5 plate with a hole cut to the size of the smaller plate, and a second with a slightly smaller aperture glued on top to hold the plate in place.Nicholas Middletonhttps://www.blogger.com/profile/09069364566487735897noreply@blogger.comtag:blogger.com,1999:blog-1573193546035756071.post-36508728949564792512014-04-07T17:59:10.549+01:002014-04-07T17:59:10.549+01:00Like the tall picture of scaffolding, very impress...Like the tall picture of scaffolding, very impressive. Why is stand developing so effective? And more questions, have you ever heard of Barnet Presstopan plates? I have some but have not had anything but black plates from them. How did you make the adapters to fit 5x4 darkslides?MattBolex7https://www.blogger.com/profile/03665843397954325241noreply@blogger.com
