Ultrafin Liquid
Development
Time and Temperature Table
Ultrafin Liquid is an all-round developer concentrate for most Black and White roll and sheet films. Processing results can be varied by the dilution of the developer concentrate. Ultrafin Liquid should be used as a one-shot developer and mixed just prior to use. Ultrafin Liquid concentrate has excellent keeping properties for up to 6 months in a tightly closed bottle.
Listed below are recommended times for processing most popular films. Depending on your enlarger type, select the appropriate table below. For diffusion, cold light and dichroic enlargers use table one (click here). For condenser enlargers use table two (click here). When processing in a JOBO rotary processor a five minute pre-soak is recommended.
All development times listed are for processing at 20° Celsius (68° F). For processing at temperatures other than 20° consult the time correction factors for various temperatures below (click here).
