Know what’s loaded. Meter your next frame. Keep every roll organized.
Lumina brings your film inventory, camera gear, roll log and light meter together on your iPhone. Spend less time checking notebooks and more time making photographs.
START WITH THE ROLL IN YOUR CAMERA
Add a camera, add your film, and load a roll. Lumina carries its rated ISO and camera calibration into the meter, then saves each exposure reading to the right roll and frame.
KNOW WHAT’S IN THE FRIDGE
See your film stocks, quantities, formats, expiration dates and storage locations in one place. Track batches and purchase costs, spot low stock, and add your own film-label photos.
PICK UP WHERE YOU LEFT OFF
See your active camera, loaded film and next frame at a glance. Follow each roll from loaded and exposed through the lab, development, scanning and archive. Keep push/pull settings, lab details and notes with the roll.
METER AND LOG THE NEXT FRAME
Choose spot, center-weighted or matrix metering. Use aperture priority, shutter priority or manual settings. Explore bright and dark areas with Exposure Map, false color, zebra warnings and a live histogram. Tap the preview to focus, then log the reading with one tap.
LiDAR distance mode is available on supported Pro iPhones. Exposure settings can be adjusted with compensation and camera calibration.
KEEP YOUR KIT ORGANIZED
Catalog camera bodies and lenses with photos, serial numbers, lens mounts, condition, purchase prices and estimated values. Keep service history alongside each camera and see what film is loaded.
YOUR COLLECTION STAYS WITH YOU
No account. No ads. No tracking. No subscription.
Film, gear, imported photos and exposure records stay in the app’s local storage. Camera and LiDAR frames are processed on-device and are not recorded or uploaded. Core features work without an internet connection.
Create a local backup, restore your collection, or export records as CSV using Apple’s system file picker. There is no automatic cloud sync; make a backup before changing phones.
Start with one camera and the roll that’s in it.
