FilmMeter vs light & deep

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.

Light & Deep is a viewfinder, light meter and LiDAR rangefinder for film, cinema and custom made cameras. Choose your format and focal length, meter the light and measure your subject distance. With Pro (one purchase, no subscription), see the estimated depth of field as zebra stripes over the live scene, and watch it change as you adjust the aperture. Originally built for a handmade camera without a finder or meter, it brings the same practical tools to medium-format, large-format and panoramic photography. SEE DEPTH OF FIELD — PRO Explore which nearby parts of your scene would be sharp for your format, focal length, aperture and focus distance. Open the aperture and the highlighted zone narrows. Stop down and it grows. METER THE LIGHT Set your film ISO, choose aperture or shutter priority, and read the corresponding exposure setting. Pro adds spot metering and calibration for each iPhone lens. FRAME YOUR SHOT Set your format and focal length to preview composition. Free offers 35mm full frame and 6x6 medium format. Pro offers 53 film, digital and cinema formats, including large format, XPan, Instax, Polaroid, Super 8, and IMAX. MEASURE THE DISTANCE On a LiDAR-equipped iPhone, tap a point to measure its distance. The free distance zebra highlights surfaces near the selected distance. Pro adds depth-of-field visualization and can keep measuring a fixed point in the scene even as you move the phone. SAVE A REFERENCE — PRO Keep a reference photo with a settings strip and image metadata. Record aperture, shutter speed, ISO, format, focal length, distance, a film note and optional location, so you can refer back to your setup later. FREE, WITH NO TIME LIMIT • Reflective light meter with aperture and shutter priority • 35mm full-frame and 6×6 frame overlays • Focal-length control • LiDAR distance measurement, tap-to-measure and target-distance zebras on supported hardware PRO - ONE PURCHASE, NO SUBSCRIPTION • Depth-of-field visualization on supported hardware • All 53 formats • Spot metering and light-meter calibration • Reference photos with settings and metadata • Fixed-point distance tracking • Ultrawide camera support on compatible devices • Black-and-white view and virtual horizon • Frame, zebra and crosshair customization • Parallax correction for a phone mounted on a camera • Cinema tools: shutter angle, project frame rate and anamorphic squeeze Pro is an optional one-time in-app purchase. The free features remain available without upgrading. REQUIREMENTS iPhone with iOS 17.6 or later. Distance measurement, distance zebras and depth-of-field visualization require a LiDAR-equipped iPhone: iPhone 12 Pro or 12 Pro Max, or a later model with LiDAR. Metering and framing work without LiDAR. LiDAR is intended for nearby subjects, with a useful range of about five metres depending on conditions. Depth coverage is limited to the central area in ultrawide view. The depth-of-field overlay estimates acceptable sharpness; it does not simulate lens bokeh or guarantee the final photograph's sharpness. PRIVACY No account, ads or analytics. Camera, depth and exposure processing happens on your device. Optional location data is used when you choose to include it in a reference photo.
