a friend is in the used printing equipmetn business and gave me some
boxes of "lith film". i haven't been able to get any information about
it at all and was wondering if anyone had any advice? (i think that
coming from the printing industry that almost guarantees that it's red
light safe.) i recently cut a sheet into 4x5's and shot two sets of six at wildly different exposures (starting with an arbitrary ASA 6 rating) then developed in dektol because it was handy. one of the images actually came out pretty good but weird. on closer inspection the weirdness turned out to be that it was positive film! (there is a certain sexiness to b&w slides and these were 4x5!) so, duh-uh, i looked on the box and sure enough it says "duplicating film". i'm thinking that it could be a lot of fun to make a big pinhole camera and have giant transparencies. am also going to try enlarging negatives onto it for giant alt-photo contact negs. i think i can design a series of tests to determine a practical ASA and more tests to determine a developer and times for development though i'd like to learn from someone else's experience if that's possible. thanks for any thoughts, advice, etc. pasha |
