Lumina: Film & Light Meter

Make every frame count. Lumina brings a light meter, film inventory, camera library and roll log together in one private iPhone app. Its adaptable layout gives iPhone Duo a roomy viewfinder with exposure readings in the sidebar. Lumina also works on other iPhones running iOS 17 or later. METER THE LIGHT Choose spot, center-weighted or matrix metering. Use aperture priority, shutter priority or manual exposure, with direct scrolling controls for aperture, shutter speed and ISO. Tap the preview to focus, check the live histogram, and fine-tune exposure compensation and camera calibration. FOLLOW THE ROLL Add your camera and film, then load a roll. Carry the film's ISO and camera calibration into the meter and log readings to the right roll and frame. Track rolls from loaded and exposed through development, scanning and archive. Keep lab details, push/pull settings and notes alongside each roll. KNOW YOUR FILM AND GEAR Organize film stocks, quantities, formats, expiry dates and storage locations. Track batches and costs, spot low stock and add your own label photos. Catalog camera bodies and lenses with photos, serial numbers, condition, purchase details and service history. SMART MODE: SCENE-AWARE EXPOSURE Apple Vision recognizes snow, beaches, portraits, backlight, sunsets, landscapes and low light on-device. Smart Mode combines the scene, your film profile and metering pattern to suggest a shutter speed or aperture. It can meter a detected face region and suggest approximate long-exposure reciprocity corrections for supported stocks. Inspect the rationale from the scene badge or turn Apply to Exposure off for suggestions only. These are estimates, not a guarantee of correct exposure. OPTIONAL LUMINA PRO One purchase unlocks Smart Mode, Exposure Map, false color, zebra exposure warnings and LiDAR distance on supported iPhones. No subscription. LiDAR requires a compatible LiDAR-equipped iPhone; it is not available on every device. Eligible users can start an optional 3-day free trial of all five Pro tools. The trial lasts 72 hours from the original Apple-confirmed trial transaction. Afterward, Pro tools lock unless you choose the separate one-time purchase at the price shown in the app. No automatic charge. Restoring a trial keeps its original dates; it does not start a new trial. Basic metering, histogram, calibration, film and gear inventory, unlimited rolls, exposure logging, local backups and CSV export remain free. Eligible earlier App Store users retain access to the advanced tools based on their verified original app version. Restore Purchases is available in Lumina Pro settings. YOUR COLLECTION STAYS WITH YOU No app account, third-party ads, analytics or tracking. Camera and depth frames are processed on-device and are not recorded or uploaded. Your collection stays in local storage; there is no automatic cloud sync. Create a backup before changing phones. Apple handles optional purchases, verification and restoration through the App Store. Lumina does not operate a payment server or upload your photographs, inventory or exposure logs. Start with one camera and the roll that's in it.
