These are the development times that I have determined for Efke PL100 sheet film using BTZS type tubes. These were developed using Pyrocat HD at a dilution of 1-1-100.

SBR 7 (n development)--11 minutes at 70 degrees

SBR 6 (N plus one development or thereabouts)--14 1/2 minutes

SBR 5 (N plus two development or thereabouts)--18 1/2 minutes

These times will give a density range of appr. 1.20. This is net density (high density minus low density...not minus FB+fog). These should work with a diffusion light source enlarger.

This film appears to have great potential as an Azo or alternative film since it builds density much faster and to a greater extent then Classic 200.
