All times listed above are values for orientation; processing unit: tray, tin, …;
Contrast: medium (g=0,65).
To get maximum Film speed or to higher nominal Film speed „pushing“ of process is possible.
Notice: When „pushing“ negatives higher contrast and lower resolution power (caused by bigger
grains in negative structure) are obtained. If negatives with high balance in contrast and grain are
required, then developer can be used in dilution of 1 + 1.
At processing temperatures lower or higher than 20 ° C, prolong or reduce processing time, as
follows:
at 18 ° C
prolong by appr. 20 %
