Detailed Tables
As long as you are using only a single size of sheet film in the Expert Drum at one time, these tables will show you the
solution quantity needed. Remember, these numbers are intended as a starting point, conditions are different in every
darkroom. Don't be afraid to experiment with larger volumes of chemicals if you think it might improve your results. For
the most consistent results, load the drum with at least half of its film capacity (5+ sheets with the 3010 for example).
The table for black and white films recommends higher levels of chemistry than the E-6/C-41 table. This is due
primarily to the higher dilutions found in black and white developers. The main consideration here is not the volume of
solution in use but the amount of actual developer in the solution. There is no easy way other than testing to determine
the precise quantity best suited for each developer. However the table below is an excellent starting point.
