Selection and detail
- Quick Cull: P/K to keep, X to reject and U to mark pending. Auto Advance is optional; Z undoes a decision.
- Hero Selects: ratings 1–5; S marks a five-star favorite.
- Fit, 100% and 200% viewing, with available EXIF camera/exposure data. 100% uses the image's natural dimensions as CSS dimensions; it does not promise physical pixel mapping on Retina screens.
- Burst groups use capture time, camera identity and parent directory. The grouping interval can be adjusted; groups can be manually split or merged. Camera make/model is the fallback when body serial is absent.
- C pins a reference. Side-by-side comparison synchronizes zoom/pan; B switches a single viewport manually between reference and candidate.
Formats and limitations
JPEG, PNG and WebP are the primary supported photo workflow. The scanner also recognizes TIFF, HEIC/HEIF, AVIF and MP4/MOV/M4V, but recognizing an extension does not guarantee decoding or full-size display. The tested Mac thumbnail/EXIF pipeline cannot fully process HEIC/HEIF/AVIF; use JPEG copies. TIFF full-size display depends on the platform's WebView. Video thumbnails require external FFmpeg; playback depends on the WebView's codecs.
Camera RAW files, including CR2/CR3, NEF, ARW and DNG, are currently unsupported. Read the RAW workflow guide.
Suggested picks use edge/exposure heuristics and filename grouping. They are not a trained AI model and do not detect faces or assess eyes. No measured 3,000-photo performance result is published.
Local files and export
Selection records and caches stay on the computer. Desktop export creates selected photo copies and XMP rating sidecars; supported crop/rotation adjustments affect copies. Source photographs remain unchanged. XMP interpretation depends on the receiving editor; there is no automatic transfer of JPEG ratings to companion RAW files.
Browser demonstration
The web workspace is a limited demonstration. It reads selected photos locally without uploading them, keeps decisions in memory and clears them on reload. It exports a JSON selection record only. Use the desktop app for photo copies and XMP sidecars.
