20X24 FILM IN GENERAL
nze-boun jour mon ami-se va?
am flying blind here since i NEVER AGAIN will ever go to thiefbay, but i ran two 20x24 klimpsch auto verticals, both the original mechanicaly coupled and the $150k computerised model, brand new in 1982
all the 20x24 materials that any body made at the time i used on a daily basis, both in camera and in contact frame
kodak direct duplicating film and kodak auto -positive are very different materials and then there are/were the agfa products and dupont products and fuji
auto-positive is a prefogged emulsion that goes to a pos from a pos but it is not easy to use because of the need for high lumen exposure-pulsed xenon is best
the direct duping films that are designed for contact frame use are basically pre fogged line film and you can use them in camera with less exacting illumination as long as you can deal with exposures of many mins-also they both are not continuos tone and require lith developers
the agfa/dupont/fuji products were all variations on this
vaya con dios
