Reciprocity data Exposure guidelines - x468 and 2470 For the Direct Duplicating Microfilms (x468 and 2470), Print density decreases with increased exposure and tungsten exposures from 100 to 0.001 seconds, and increases with added development for the direct processing in a Kodak Prostar Processor as duplicating microfilms. For intermediate duplicating recommended, reciprocity failure is negligible and no masters, generally the D-min in the master should be correction is normally needed. Simi

Replenishment rates Before-process handling and storage Development/transport time and transport rates are set Handling to achieve desired photographic aims; replenishment Total safelight exposure, whether before or after image rate settings are determined by multiplying the exposure, should not exceed 30 minutes. For transport speed by the required replenishment rates for darkroom handling, x468 and 2470 Microfilms should the appropriate film width being used. use a Kodak 1 Safelight Fil
