The core idea: give every roll an identity the moment you load it — a name, the camera it's in, and the date — then keep that identity with the roll until the negatives are filed. Do that consistently and the confusion disappears.
Why rolls get confusing
Film gives you almost no feedback. A wound-back canister looks identical to a fresh one, a half-shot roll in a paused camera has no counter you can trust after a battery pull, and a box of exposed rolls waiting for the lab all look the same. Multiply that by two or three cameras and a few film stocks and it's easy to lose the thread.
A system that works
Name the roll when you load it
Give it something you'll recognise — "Portra 400, Leica, city walk" — plus the date. The name is what ties the physical roll to your notes later.
Record which camera it's in
This is the "which roll is in which body" answer. Note the camera at load time, and you'll never open the back on a half-shot roll again.
Mark it active while you shoot
Keep a short list of rolls currently in cameras. When you finish one, move it from "active" to "shot — to develop."
Label the canister after rewind
A bit of tape and the roll's name on the exposed canister keeps the identity attached until it reaches the lab. Add "push/pull" here if you shot it at a different EI.
Match it back to your notes when scanning
The roll name on the canister lines up with the roll in your notes, so every frame's settings and locations are right there as you scan.
Paper, phone, or app?
Any of these work — the trick is consistency, not the tool.
- Paper. A pocket log sheet per roll is cheap and battery-free. If you like this, grab our free printable film log template.
- Phone notes. Fast to start, but they get messy across many rolls and cameras, and there's no structure to read back.
- A dedicated app. Keeps every roll named, dated and tied to a camera, shows which rolls are active, and stores it all so nothing gets lost.
How Film Logbook handles this
Film Logbook is built around exactly this problem. Each roll records its camera, lens, film stock, ISO and a name; you can see your active rolls at a glance; and everything is stored privately on your device and your own iCloud, so a lost phone note never loses a roll. When you develop, the roll — and every frame's settings and locations — is waiting for you.
Never lose a roll again.
Free on the App Store. Free for up to two active rolls; one-time €5.99 Pro for unlimited.
