FilmMeter turns your iPhone into a professional light meter for film cameras. Real-time metering, LiDAR ranging, reciprocity calculation, and exposure logging — one app covers your entire shooting workflow from loading film to the final frame. Metering Measure exposure in real-time using your iPhone camera. Spot metering reads any point precisely, while average metering balances the whole scene. Full control over aperture, shutter speed, and ISO. iPhone 16 users can meter and adjust EV directly with the Camera Control button. Ranging & Depth of Field Get accurate focus distance with LiDAR-enabled devices. The depth of field scale shows your sharp range and hyperfocal distance, supporting 35mm (full frame) and medium format calculations. Camera Management Create profiles for your cameras and lenses. Set focal length and aperture range for each lens, then link a camera when loading film — aperture selection is automatically constrained to your lens's actual range. Manage your digital film bag the way you manage your real gear. Film Roll Management Create a roll, select your film stock, start shooting. Push/pull processing support lets you set development stops and automatically converts to effective ISO. Each metering links to your current roll automatically. The frame counter tracks remaining shots. Mark rolls as in progress, finished, or developed. ND Filters Built-in support for ND2 through ND10000. Select a filter and exposure is compensated automatically — no manual stop conversion needed. Pair with the long exposure timer to master daytime slow shutter work. Reciprocity Compensation Film loses sensitivity during long exposures. FilmMeter includes reciprocity data for popular film stocks and calculates the corrected shutter time automatically. Long Exposure Timer Long-press the metering button to start a countdown. The timer integrates with Dynamic Island — visible even when locked. Get notified when your exposure completes. No more counting seconds for star trails or light painting. Smart Exposure Suggestions Built-in scene recognition analyzes your frame. In tricky lighting like snow, backlight, or night scenes, it tells you "add one stop" instead of leaving you to figure it out. Exposure Log Every metering saves full parameters and location. Export to CSV. Review your decisions, build your film notes. More Features • ND filter auto exposure compensation • Film LUT live preview • Aspect ratio overlays (135/120 formats) • Focal length frame lines (28-200mm) • Darkroom-friendly red-on-black interface • Metric and imperial units Free to Use • No subscription, no account required • Fully offline, no ads • English and Chinese Designed for film photography. Professional enough for experienced shooters, simple enough for beginners.
