Emulsion Log: Film Logbook

The film photography log for shooters who still load a roll — an analog film tracker for 35mm film and 120 that keeps every roll, every frame and every setting in one private, offline logbook, and then matches your notes back to your scans when the film comes home. Emulsion Log is a film roll logbook built around the way film actually works: you load a roll, you shoot it frame by frame, you unload it, and weeks later the scans arrive. The log holds both halves. Nothing else in the category closes that gap. LOG THE ROLL IN ONE SHEET Film stock, ISO, exposures, camera, lens, format, push or pull — one sheet when the roll goes in. The count then runs itself: every frame you log advances the counter, and the roll knows when it is full. LOG EVERY FRAME IN SECONDS Frame number, shutter, aperture, EV compensation, metering mode and a note — manual first, every field explicitly set or explicitly blank. The frame number is written by the log, never typed, so the counter cannot drift from the sheet. Undo takes the last frame back; skipped frames are recorded as the blanks they were. EXPOSURE LOG THAT STAYS IN ORDER Film photography is a discipline of notes. "Portra 400 at 800, one stop pushed, 1/125 at f/2" is the whole reason a logbook exists, and every frame carries its own record in tabular mono columns that line up like a contact sheet. THE CONTACT SHEET The screen no other film app has. Your roll as a grid of negatives, six across, one cell per real frame. A logged frame is an exposed cell waiting; a frame with a scan is a print. Scan match fills the sheet from your camera roll in frame order — the shot-to-scan gap closed in one tap. FIGURES FOR THE ANALOG SHOOTER Rolls shot, frames logged, your most-used stock, the busiest month, per-stock and per-camera tallies. Pro opens the figures and the scan match; the log itself is never held back. YOUR DARKROOM, ON YOUR PHONE Warm paper, one safelight, black rebate. The app is built to feel like the notebook that comes back from the lab, not another camera simulator. FREE MEANS THE WHOLE LOGBOOK Every roll, every frame, every note is free, unlimited, forever. CSV export and JSON backup and restore are free too — a logbook you cannot get out of is a lock-in, whatever the paywall says. No account, no sign-up, no analytics, no sync. The log never leaves your phone unless you export it yourself. One-time purchase. No subscription, no ads, no account. Load a roll. Emulsion Log: Film Logbook.
