WINDER

FOR HALF-FRAME CAMERAS · PENTAX 17 · OLYMPUS PEN · EKTAR H35

Two frames
in every shot.

Your lab returns two photos welded into one 35mm scan. Winder finds the bar between them, cuts clean, straightens each shot, and files the roll like it deserves.

THE WIND-ON

Import. Split. File.

01

Import scans

Drop in the JPEGs from your lab or scanner — one file, two shots, no metadata. Batch as many as you like.

02

Review the cut

Winder detects the black divider automatically. Nudge it with your thumb, rotate each half, keep or discard.

03

Tell the story

Stamp the roll with date, place, camera and film — the lens fills itself in from the camera model. Done: two frames, filed.

FILES, NOT A DATABASE

Your library is a folder.

Albums are folders. Every detail lives in a small JSON sidecar next to its photo — like Obsidian, but for negatives. Point it at iCloud Drive, Dropbox or WebDAV and your library follows you. No lock-in, no export button needed, ever.

  • Rename a folder in Finder — the album is renamed
  • Sidecars are human-readable JSON
  • Deletes go to .trash, never oblivion
  • Syncs with anything that syncs files
