Photography Timer is a practical timer for long-exposure photography. It helps you calculate how much longer your exposure becomes when using ND filters, and also check reciprocity failure correction times when shooting long exposures on film. Key features: • Long-exposure photography timer • ND filter exposure time calculation • Film reciprocity failure correction • Multi-camera timers • Start timers from calculated times or custom target times • Check active and completed timers during a shoot • 34 film presets supported: ILFORD/HARMAN, Kodak, Fujifilm, FOMA BOHEMIA, Rollei, ADOX • Custom film profiles for saving your own correction data Film data note: based on official manufacturer materials, technical documents, product PDFs, support pages, and other reviewable sources. Photography Timer is made to reduce exposure calculation work in the field, so you can focus on the actual shooting time. I built this app because I needed it for my own photography. It started from my workflow with tripods, ND filters, film cameras, and long exposure times. If your photography workflow is different, I would be happy to hear what would make the app more useful.
