    Re: Looking for a film that can be shot at low asa ( 1 or 2 )

    Hey guys. Thanks for all the responses. I own an SP445 so I’m excited about being able to develope plates in one.

    The artist name is Whitney Lewis Smith http://www.whitneylewissmith.com Pretty sure she uses dry plates as she stated the exposures run around 6 minutes.

    I’m super interested in how she got the viscous tortuous effect in her backgrounds. I accidentally achieved this effect developing some tmax 100 last year but haven’t been able to reproduce it.

    She is a full time professional teaching alternative processes and coats her own plates. It's hard to say exactly which process she is using, but if I had to guess there are several. Some look like wet plate, some look like a sort of dry plate. I have got results similar to what she has a few times. However, most all of my exposures are 1/2 to 2 seconds. I've never had one run over 2 minutes. That suggests wet plate to me. As was said above, the length of exposure really isn't the thing here. I think I could come close to the results with just the Lane dry plates, but those have significantly fewer imperfections than what Smith is doing. Lens selection is also a part of the equation. I never use lenses no newer than 1925 for glass plates, and most of my lenses were made before the Civil War.

    Is achieving that viscous effect simply a result of coating the plate with a specific chemical? Also I’m assuming that the long exposures are simply a result of an asa of 1. Just metered a scene and my light meter only goes down to 3. Got a 4s exposure up to a minute so with reciprocity and lower light and an ASA of 1 a five minute exposure makes sense.

    I’m interested in the abstract effect that chemicals from these processes impart.

    IDK
    the subjects look like they were in open shade and the background was bright
    i get that sort of thing all the time without
    gigantic exposures like you mention, or dry/wet plates.
    while it seems she coats dry plates..
    you might not need to deal with glass images ... i am able to get images like that
    with film + paper negatives ... its all in the lighting and blocking-up the background
    by a few stops... caffenol c and print developer working together can give you the
    density and slow developing you need to get that sort of effect. it says in her bio
    that she not only uses the glass images, but she sometimes scans them and adjusts them in PS.
    using PS makes it easier to adjust the forground levels without screwing up the blown out background.



    ( have fun + ) good luck !

    is extremely slow like BELOW iso 1.
    i've never exposed it in camera ( only under a bright light ) it might be something ...
    .. the other emulsion you might think about is on azo paper. super slow, again, below iso 1
    usually found online odd sizes, old and cheep. don't forget, with paper negatives a little fog is your friend...
    lastly you might also look at this>> http://thelightfarm.com/Map/DryPlate...yPlatePart.htm
    super slow very easy to make ( and from what i remember if you are coating it on paper you don't need
    to wash it. ) don't let the emulsions with the descriptor "dry plate" fool you,
    you can coat them on anything, just like liquid light, aj-12
    foma, formulite, luminous and the rest of them ...
    they are just non-panchromatic s/g emulsions ( paper, plate &c ) in a bottle...

    be careful if you make your own .. eyeprotection is a necessity ... and once you start making
    emulsion its kind of an addiction.. now you know why nodda duma is coating plates and selling them, he
    can't find a 12 step program to get him off the SGE up in his neck of the woods !
