I have a Unicolor drum and motorized base that I use for processing 4X5 B&W film . I could put up to four sheets into the tank but I only do two because the fil m overlaps during processing. The solution looks like some type of spacer "thin g" to keep the two film sheets on each side of the tank apart. Does anyone know if Unicolor or someone else makes such spacers?
The tank and drum work great, are extremely economical to use (90ml of solution for two sheets) and produce exceptionally even development. I'm just lazy and w ant to do more film per run!
