The fastest way to cull thousands of photos

A focused macOS culling app for photographers who select by hand. Rate with stars and colors at full speed — keyboard or even a game controller — while everything saves to standard XMP sidecar files. Your originals are never moved or modified.

What is Speed Contact Sheet?

Speed Contact Sheet is a macOS photo culling app built for photographers who shoot in volume — weddings, events, portraits, sports — and need to get from thousands of frames to a clean selection as quickly as possible. It is a dedicated culling tool, not an editor: its only job is to help you decide which photos to keep, reject or flag, and to do that faster than anything else in your workflow.

Every rating is written to a standard XMP sidecar file, so your selections flow straight into Adobe Lightroom, Capture One or Adobe Bridge. The app never moves or modifies your original photos.

Where culling fits in your workflow

Culling is the first pass — the part most photographers dread. Before a single photo gets edited, someone has to look at every frame and decide what stays. On a big shoot that can mean reviewing 8,000 images one by one. Speed Contact Sheet is built for exactly that step, and nothing else. By doing one job well, it gets you to your keepers faster, then hands them off to whatever editor you already use.
