About Lumen
Lumen reads the light through your phone camera and gives you an exposure you can dial straight into your film camera. Choose your film speed once, and it keeps the aperture or shutter speed you care about fixed.
What Lumen does
- Spot and average metering
- Tap the part of the scene you want exposed correctly, or meter the whole frame.
- Aperture or shutter priority
- Lock the setting you care about and Lumen works out the other one.
- Real camera stops
- Results snap to the full, half or third stops your camera actually has.
- Shot notes
- Save the settings for each frame with the roll, lens and a short note.
