Cull: Photo Picker
Photo Culling Studio
Free · In‑App Purchases
Cull thousands of RAW photos in minutes. On-device AI scoring, face & blur detection, burst grouping, and one-click XMP export to Lightroom.
Cull is the fastest way to go from a full memory card to your best shots.
Import a shoot, fly through your photos with keyboard shortcuts, and export
your picks straight to Lightroom — all without your photos ever leaving your device.
CULL FASTER THAN EVER
Press P to keep, X to reject, and move to the next shot automatically. Cull
hundreds of photos in minutes instead of hours. Every action has a keyboard
shortcut so your hands never leave the keys.
FOUR POWERFUL VIEWS
• Grid — scan your entire shoot at a glance with adjustable column density
• Loupe — full-screen single photo view with a floating filmstrip for quick
navigation
• Compare — two photos side by side to pick the better expression or moment
• Burst — automatically groups burst sequences and surfaces the best frame
using AI scoring
ON-DEVICE AI SCORING
Every photo gets an AI quality score powered by Apple Vision — running 100%
locally on your Mac's Neural Engine. No cloud, no subscription, zero privacy
cost.
• Face shots scored on capture quality, eye openness, and focus
• All other photos scored on aesthetics and sharpness
• Blurry photos automatically flagged for rejection
• Adjust the rejection threshold to match your standards
COLOR LABELS
Tag your keepers with Lightroom-compatible color labels (Red, Orange, Yellow,
Green, Blue, Purple) directly in Cull. Labels carry through to Lightroom on
export.
EXPORT TO LIGHTROOM
One click writes XMP sidecar files for all your keeps — Lightroom reads them
automatically when you import, so your picks, ratings, and labels are already
applied. No plugins, no manual tagging.
DESIGNED FOR RAW SHOOTERS
Cull works with every format your camera shoots: RAW (CR3, ARW, NEF, DNG,
RW2, ORF, and more), JPEG, HEIC, and TIFF. Files stay exactly where they are
on disk — Cull never copies or moves your originals.
PRIVACY FIRST
All AI analysis runs on your Mac using Apple's Vision framework. Your photos
are never uploaded anywhere.
ONE-TIME PURCHASE
Pay once, cull forever. No subscription.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
SCORING YOU CAN ACTUALLY READ
- Scores now show why: badges for eyes closed, blinking, soft focus, poor exposure, and screenshots/documents — visible in the grid, loupe, and burst review.
- Scoring no longer dumps photos into flat piles of 30 or 20. Penalties now scale proportionally, so ordering stays meaningful even within a group of flawed shots.
- Sharpness is measured on the subject's face when there is one, so shallow-depth-of-field portraits and busy backgrounds no longer throw off the score.
- Blink detection is per-face — one person blinking in the back of a group shot is a note, not a score-killer. Only the main subject's blink counts against the photo.
- Exposure scoring now catches flat, muddy under/overexposure, not just clipped highlights and shadows.
- Score colors are now relative to the shoot, so a dim indoor set doesn't read as uniformly yellow.
- The loupe shows "Top N% of session" plus separate Technical and Aesthetic scores.
BURSTS AND SCENES
- Burst grouping now clusters by capture time first, so similar-looking shots from different moments stop getting chained together — and it's dramatically faster on large shoots.
- The best frame in a burst is picked using signals that actually differentiate near-identical shots (face quality, subject sharpness, eyes), not just the overall score.
- Fixed a bug where starring a frame in burst review was ignored — "Keep Best, Reject Rest" now respects your pick instead of overriding it with the AI's.
- New Scenes view groups your grid into shooting scenes with headers.
CULLING
- Suggest Rejects is now tiered: the first tap flags only definite rejects (screenshots, main-subject blinks, badly missed focus); tap again to widen to borderline shots.
- Photos rated 4 stars and up are never suggested for rejection.
- Cull now learns from your culling decisions on-device and gradually adapts to your taste. Toggle and reset it anytime in Settings — nothing leaves your Mac.
LIGHTROOM & METADATA
- Export no longer overwrites your existing .xmp sidecars. It used to wipe develop settings, crop, white balance, and GPS — it now patches only its own fields.
- Metadata is written where Lightroom actually reads it: inside the file for JPEG/HEIC/TIFF/PNG, sidecars for RAW. Previously, sidecars written for JPEGs were invisible to Lightroom.
- Star ratings are read from your photos, editable right in the loupe, and written back on export.
- Sidecars now follow photos into keeps/rejects instead of being left behind in the original folder.
- Color labels now survive closing a session.
