Read full description

Speed Contact Sheet is the fastest way for professional photographers to cull and rate an entire session โ€” thousands of frames โ€” and reach a clean selection with no imports, no copies, and no waiting. Your originals are never moved or modified. WHAT MAKES IT FAST โ€” Designed for touch, on iPad and iPhone Not a desktop tool squeezed onto a phone. Swipe to rate, swipe to move between frames, pinch to zoom up to 5ร—. Your hands stay on the screen and your eyes stay on the photo. โ€” Straight-from-the-card workflow Connect a card reader to your iPad, open a folder, and start rating. No catalog to build, no background import. Every rating is written the instant you make it, right next to each photo. โ€” Ratings that travel anywhere Stars, color labels, and flags are saved as standard XMP โ€” embedded in the JPEG or as a sidecar beside your RAW. Your selections flow into any professional editing or asset-management pipeline. No lock-in, no proprietary catalog. โ€” One workflow across Mac, iPad, and iPhone Start in the field on iPad, finish in the studio on Mac. Turn on private iCloud sync and your uploaded photos and their ratings flow to their final destination automatically. Rate on one device and the latest rating is pulled back to the others on its own โ€” so you never lose your selection progress. All through your own iCloud, never our servers and never a third party. โ€” Burst detection, done for you Rapid-fire sequences are grouped automatically, and a built-in sharpness analyzer surfaces the crispest frame so you only judge the contenders. โ€” Cull hands-free, stay in your flow Full game-controller support: map navigation and ratings to a controller and keep your rhythm without ever looking away from the photo. Complete keyboard shortcuts on Mac, too. โ€” Stay in the zone An optional built-in focus timer keeps your attention sharp through long culling sessions. PRIVATE BY DESIGN Your photos and ratings live on your device. Optional iCloud sync stays inside your own private iCloud. No ads, no tracking, no third-party servers, no separate account to create. BUILT FOR โ€” Wedding and event photographers culling thousands of RAWs from a single day โ€” Sports and action shooters pulling the keepers out of long bursts โ€” Editorial and portrait photographers who deliver same-day โ€” Anyone who'd rather trust their own eye than let software decide Speed Contact Sheet. Built by a photographer, for photographers. SUBSCRIPTION Speed Contact Sheet is available with a subscription after a free trial. Payment is charged to your Apple ID at confirmation of purchase.
