[LargeFormat] Processing 4X5 recommandations.

[Frank Filippone]

I use 300ml ( diluted volume) per 8x10 sheet of TMaxRS diluted 1:4 and 1:5.

Times are 4 1/2 minute at ASA 100 for Tmax100 film at 75 degrees in a JOBO.
2509n reel... not the fancy 3010.

I develop only 4 sheets of 4x5 per  run, or 1 roll of 135x36 or 120 film.
There is no developer problems at these dilutions....  Sexton uses 600 ml in
his JOBO......the 3010 expert models..... at a dilution of 1:9.

If you were to work this out, there is about 60ml of concentrated developer
per 8x10.  Same as Sexton.... less than this causes developer
exhaustion..... or so it seems in my darkroom....
