Sheet film daylight developer for 4' x5" and 8' x 10" black and white sheet film (Assembled).
3 part developer tube for single 4" x 5" sheet film. The longer tube holds the film, the center piece is the light stop, and the smaller piece is the cap to allow changing the chemicals during processing. This tube requires only 2 ounces of developer per sheet.
The parts of an 8" x10" daylight development tube of the same basic design. 3" ABS tubing and sheet. 3 round flat sheet of ABS cut to the pipe diameter and cut at a chord to allow liquid to pass through. 2 3" ABS end caps., 1 @ 10" tube, 2@ 3" tube, 2 3" connectors, ABS glue. An 8" x 10" and 4" x 5" film holder are included for scale.
Affix the flat piece to the end of the 3" section of tubing with the ABS glue and sand to reduce the flat to the size of the pipe.
Alternate the openings at 180 degrees on each end of one of the short sections of tubing. Affix the third piece to the end of the other 3" section of tubing.
Assemble and glue the pieces into three assemblies.
The construction of the 4" x 5" daylight developer is the same as the 8" x 10" except that it uses 1 1/2" ABS pipe instead of 3".
To use this, in a darkroom or dark bag, place the exposed film emulsion side in, into the long tube and put the light stop section onto the end of the tube to make it light safe. Add developer (> 8 ounces for 8x10 and >2 ounces for 4x5) and cap the end. In a tray roll the tube for the appropriate development time. When complete remove the end cap and dump the chemicals, add stop and cap, roll to agitate. Repeat with fixer and rinse.
