Darkroom Formulas

Darkroom Formulas contains a database with over 160 chemical formulas from Digitaltruth.com including film developers, print developers, toners, reducers, intensifiers and more. Users can edit existing formulas or add their own favorite recipes. 

The app contains a powerful Volume Mixer allowing all ingredients to be adjusted proportionally on-the-fly. No more messing around with complex calculations, simply change the final volume and every ingredient changes automatically! 

Your own saved formulas can be exported and shared by email, or stored externally as a back up.
