Before digital, photographers reviewed their work on a contact sheet. A roll of film was cut into strips and laid directly on photographic paper. Light passed through the negatives, and the paper was developed, producing a grid of small positive images. The contact sheet showed every frame on the roll, in order, at a glance. It was a tool for editing, for comparing, and for remembering what was on the roll.

Photographers used grease pencils to mark the frames worth printing. A slash meant maybe. A circle meant yes. The contact sheet was the first edit. It revealed patterns in a shoot, mistakes, and unexpected successes. Some photographers treated contact sheets as works of art in themselves. The photographer's choices, the sequence, the marks, all became part of the record. Today, digital photographers use software to create similar grids, called contact sheets or proof sheets. The principle is the same: see everything at once, then decide what deserves attention.

Why contact sheets matter

• Overview. See the whole shoot at a glance.
• Comparison. Compare similar frames side by side.
• Editing. Mark the keepers and discard the rest.
• Archive. A record of what was shot and when.

Contact sheets are slower than scrolling through a screen. That slowness is part of their value.
