PROCESSING
The following starting-point recommendations are
intended to produce a contrast index of 0.56. Make tests
to determine the best development time for your
application.
Note: Tank development times shorter than 5 minutes
may produce unsatisfactory uniformity.
MANUAL PROCESSING
Small-Tank Processing (8- or 16-ounce tank)
With small single- or double-reel tanks, drop the loaded
film reel into the developer and attach the top to the tank.
Firmly tap the tank on the top of the work surface to
dislodge any air bubbles. Provide initial agitation of 5 to 7
inversion cycles in 5 seconds; i.e., extend your arm and
vigorously twist your wrist 180 degrees.
Then repeat this agitation procedure at 30-second
intervals for the rest of the development time.
Large-Tank Processing (1/2- to 3 1/2-gallon tank)—
Rolls and Sheets
Agitate continuously for the first 15 to 30 seconds by
raising and lowering the basket, rack, or spindle 1/2-inch.
Do not agitate the basket, rack, or spindle for the
remainder of the first minute. Then agitate once per
minute by lifting the basket, rack, or spindle out of the
developer, tilting it approximately 30 degrees, draining it
for 5 to 10 seconds, and reimmersing it. Alternate the
direction of tilting the basket, rack, or spindle.
