Why a contact sheet

The proof, is the work.

Proofing used to be a discipline. The roll came back as a contact sheet — every frame, small and honest, on one page — and the editor bent over it with a loupe and a chinagraph pencil and looked. Ticks for the maybes, circles for the picks, a hard cross through the frames that lied.

Proof brings that pause back. Your frames as a contact sheet, your eye and a wax pencil. Development can wait until you've seen.

01 · The contact sheet

Your roll,
laid out.

Open any folder and choose which frames go on the sheet. RAW and JPG land together, sorted and filtered by type and date.
