Scanned film arrives as a blank slate.

Labs and scanners rarely know which camera, lens, film stock, or location made a photo. After import, a roll can look beautiful in Photos while its metadata is missing or wrong.

Latham turns that repetitive cleanup into a reusable preset workflow, so the information behind the image stays with the archive.

One preset, a whole roll.

Create the metadata once, select the scans that belong together, and apply the edit without exporting files or leaving the iOS photo library.

01

Create a preset

Save camera, lens, film, scanner, date, location, creator, copyright, and notes for a repeatable setup.

02

Select the batch

Browse your library, use metadata signal filters, and choose the scans that should receive the same information.

03

Write it back

Latham writes metadata directly to selected JPEG and HEIC photos through the iOS photo editing pipeline.

Named for the loop that keeps film moving.

Latham takes its name from the Latham loop inside film projectors: a small curve that absorbs tension between intermittent motion and continuous feed, keeping film from tearing.

This app plays a similar role between analog capture and digital archive. It helps the details of a roll survive the transition into Photos.
