SpeedCull docs.

SpeedCull is a keyboard-first macOS app for culling large RAW shoots quickly. This archived reference covers the early 0.1.0-mvp developer edition: workflow phases, view modes, Keeper Mode and manual XMP sync. It is retained for that edition and is not a statement of current App Store behaviour.

Quick start

If this is your first time, work through the docs in this order:

  1. Getting started — install, open a folder, run your first scan.
  2. The five workflow phases — how Scan → Generate → Cull → Sync → Cleanup fit together.
  3. View modes — Loupe, Grid, Compare 4-up, Play.
  4. Keeper Mode — multi-select bursts and promote the strongest frames.
  5. Lightroom sync — get your ratings into Lightroom Classic.
