I process 2 3 cut film in a yankee adjustable tank for sheet film. It adjusts for 2x3 3x4 or 4x5. Loading is done in the dark , put on the top and turn on the lights. A word of caution: I found it necessary to reduce development time 15% when tray developing in D 76 to keep the contrast normal. Could you tell me where you get your 2 X 3 film? A possible source for the kind of tank I use is Photophenilla on Medium & Large Format site, also Terrys darkroom some times carries older tanks. They may still be in production I am not sure,(posted 9258 days ago)
