RawCull Documentation

RawCull

RawCull is a native macOS app for reviewing and culling photo catalogs before editing. It helps you scan a folder, review thumbnails, mark keepers and rejects, score sharpness, group similar burst images, and copy selected RAW files to a final folder.

RawCull is not an image editor. It reads your files and copies selected images for use in apps such as DxO PhotoLab, Lightroom, or other editing software.

Requirements

Install

Install RawCull from the Apple App Store, GitHub Releases, or Homebrew:

brew tap rsyncOSX/cask && brew install --cask rawcull

GitHub releases are signed and notarized by Apple. The GitHub release may be newer than the App Store release.

Supported Files

RawCull primarily targets Sony ARW files. The current app also recognizes Nikon NEF files and JPEG/JPG files where supported by the workflow.

Camera Compatibility

Sony support includes EXIF, thumbnails, focus points, sharpness scoring, and saliency for tested full-frame bodies.

Nikon support is experimental. EXIF, thumbnails, sharpness scoring, and saliency are available for current Z-series workflows; focus point extraction is not currently available.

Privacy

RawCull runs sandboxed, works offline, and does not use analytics, telemetry, cloud sync, or network access. Your photos, ratings, settings, and cache files stay on your Mac.
