Graupe is the essential companion for film photographers. Whether you're loading a fresh roll of Portra or dialing in exposure for a long night shot, Graupe keeps all your analog tools in one place. **Light Meter** Use your iPhone camera as a real light meter. Choose between spot and average metering, dial in EV compensation, and work in aperture-priority or shutter-priority mode. The live viewfinder shows your scene while Graupe calculates the correct exposure — no separate meter required. **Depth of Field Calculator** Visualize your depth of field before you shoot. Select your lens, aperture, and focus distance, and see a live diagram showing near and far focus limits, hyperfocal distance, and circle of confusion. Supports all major formats: 35mm full frame, APS-C, medium format, and large format. **Film Roll Tracker** Never lose track of a roll again. Log every roll you load — what camera, which lens, which film stock — and follow it through your workflow with status badges: In Use, Finished, Sent to Lab, Scanned, and more. Add custom statuses to fit your process. **Equipment Library** Build a library of your cameras, lenses, and film stocks. Store custom shutter speed sequences for each camera body, and define exact aperture steps for every lens. The DOF calculator and film tracker pull from your library automatically. **Made for Film Shooters** Graupe is built around the analog workflow, not against it. The interface uses a film-grain texture, warm amber tones, and a typographic style that feels at home in a darkroom. Customize fonts, accent colors, and backgrounds to make it yours. Note: Graupe is provided as-is for personal, hobbyist use. No guarantee is made as to the accuracy of any readings, calculations, or data displayed. Do not rely on this app for professional, commercial, or critical photographic work.
