Lensgrade: Photo Culling

Find your keepers, keep your reasons, and carry your comparisons with you. Lensgrade combines on-device photo analysis with manual side-by-side review. NEW IN 4.0 • Back up a Keeper Desk session with its preview photos, decisions and notes. Restore it as a separate session without replacing existing work. • Search photo labels and notes, filter by Keep, Maybe, Pass or Undecided, and step through the matching review queue. • Undo the most recent saved decision or note edit while reviewing a session. • Clearer type, improved contrast, and lighter native field-reference cards. Keeper Desk adds saved photo comparison sessions with linked detail controls, your own keep/maybe/pass decisions, and a shortlist contact sheet. HOW IT WORKS 1. Open Keeper Desk from the Score tab. Try the clearly labeled five-photo example or choose 2–12 still photos. 2. Choose the two frames to compare. Use linked zoom and relative crop controls, optionally hide names and prior decisions, then mark side B Keep, Maybe or Pass and record a reason. 3. Resume the saved session, revisit undecided frames, and preview the contact sheet of kept photos. Share its PDF with a CSV containing all decisions, notes and source hashes. Existing sharpness scoring, batch analysis, focus maps, exposure information, history and field references remain available. Keeper Desk adds local preview storage and corrupt-file protection. WHAT TO KNOW Decisions are manual. Linked crops do not align subjects or measure focus. Saved JPEG previews have a maximum 2560-pixel long edge and are not original-resolution inspection or original exports. Single still inputs up to 32 MB and 120 megapixels; 2–12 photos per session, 10 sessions and 120 MB of saved data. Original Photos items are never edited or deleted. iPhone and iPad. Backups contain reduced-size previews and decisions, not original photos. They leave the app only when you choose to export or share. Restore accepts Lensgrade session backups up to 68 MB. Session and storage limits also apply to restored copies. No account, ads or subscription. Analysis scores are heuristic comparison aids affected by texture, noise and editing. They do not diagnose focus errors or guarantee print quality. Earlier saved scores are retained and marked for re-analysis after the 4.0 scoring correction.
