Development times are taken from official manufacturer datasheets and trusted published sources. The app also links to the original datasheets where available.
How does push and pull affect the time?
DevelopFilm adjusts times using standard push and pull multipliers, based on common darkroom practice and manufacturer guidance when available. You can always override the final time.
Why can times differ between people?
Temperature accuracy, agitation style, tank type, dilution, and water chemistry can all shift results. Treat times as a starting point, then log what worked for your setup.
Can I add my own times and notes?
Yes. You can save your own adjustments, notes, and results in the journal so you can repeat the look later.
