MatchGrain
Open a roll, choose lens, add a frame, optionally note important details. Seconds per shot.
A logbook for film photographers
Shoot film.
Keep every detail.
Film cameras don't record dates, locations or settings. MatchGrain logs every frame as you shoot — then writes real metadata back into your scans.

The problem
A scan is a photo
with no memory.
When a film comes back from the lab, every frame carries the same wrong date and no location. No camera, no lens, no exposure. MatchGrain closes the gap between the shutter and the scan — so a roll shot in Rome in April actually says so.
How it works
Three steps, one clean roll.
Select folder with developed scans. It lines them up against your log where you can edit to match them perfectly.
Process the roll and every scan gets real date, camera and location - saved to your library or into files.
