Filling Quantity
The actual amount of chemicals needed will depend on three factors; the amount of film surface being processed, the
chemicals being used and the minimum solution level required by the Drum for proper solution coverage. The tables
below provide a concise way to select the minimum chemical requirements for most processes. But some processes
(particularly dilute black and white developers) may require higher solution levels in order to have sufficient active
chemicals for the surface area to be processed. Use these tables as a starting point. If the initial test results indicate
chemical exhaustion, increase the solution levels.
Note: For intermediate filling quantities on ATL processors, select the next higher quantity on the ml dial.

Film Processing
For each film size we recommend the following quantities of chemistry as a basic guideline for practical use.

Basic Film Table
Film Size E-6 / C-41 B & W
4 x 5" 33 ml 50 ml
5 x 7" 57 ml 85 ml
8 x 10" 126 ml 200 ml
8 1/2 x 12"
162 ml 240 ml
Caution: Never use a quantity of chemicals less than the Expert Drum minimum quantity. It must have at
least the minimum quantity to properly cover the films or prints in the drum.

Paper Processing
The #3004, #3005 and #3006 Expert Drums are easily used for paper processing. Papers should be loaded, the same
as film with the emulsion to the inside of the tube and away from the tube wall.
Minimum Chemical quantities as listed on the table should be maintained. Apply the following quantities of solution per
8x10" print, and use either the minimum chemical quantity listed for the specific Drum you are using, or the quantity
computed from this list, whichever is higher.
For each print size we recommend the following quantities of chemistry as a basic guideline for practical use.
