How to Cull Photos in Lightroom: Flags, Stars, Compare and Survey

A limit of this page. Adobe's help site (helpx.adobe.com) could not be read while researching it (source inaccessible, HTTP 403). Nothing below about menu paths, settings names or version behaviour is taken from it. The Lightroom behaviours described are long-standing interface features; the one AI feature described comes from an Adobe page that was readable.

The core tools

Lightroom Classic gives you three simple marks and two views for culling. Learn these before adding anything else.

• Flags: Pick, Reject and unflagged. P, X and U set them in the Library module. Rejected photos show dimmed in the grid. A Reject flag is a mark, not a deletion; if you later use a remove command, read the prompt carefully, because removing from the catalog and deleting from disk are different choices.

• Star ratings: 1 to 5, set with the number keys. Stars are good for a second round, such as "5 = best of moment".

• Compare view: two photos side by side, with one as the candidate you keep or swap. Good for choosing between two near-identical frames.

• Survey view: several selected photos tiled together, from which you remove the weaker ones until one or two remain.

• Library filter bar: filter the grid by flag, star rating or label so that after each pass you see only what is left.

• Colour labels: a third channel, handy for something like "send to album" that does not collide with stars or flags. The Lens Lounge, a photographer's guide, calls colour labels the least common method; that is its opinion.

• Grid and Loupe: Grid for scanning bursts, Loupe for judging a single frame.

Check in Adobe's help: where the filter bar is on your version, the exact shortcuts for Compare and Survey, and whether flag state is saved to the XMP sidecar (relevant if another program reads your flags).

A two-pass workflow

A flag pass followed by a comparison pass is a common approach, and this page suggests it over judging every frame once and carefully (a judgement, not a measured result). This follows the multi-pass logic in how to cull wedding photos; here it is mapped to Lightroom tools.

Pass one: reject.

1. Import and let previews build (see the next section).
2. In the grid or loupe, press X on clear failures: misfires, missed focus, obvious blinks. Do not pick yet.
3. Filter to hide rejects. What remains is everything not judged a failure.

Pass two: pick.

1. Work in sequence order by capture time, section by section of the day.
2. For each moment, select the similar frames and open Survey; remove the losers until the best remain. Use Compare for the final pair.
3. Press P on the winner. Optionally give it a star for a later round.
4. After the pass, filter to Picks and review what you have against your shot list.

Do not remove rejects from the catalog or disk until the gallery is delivered. Filtering them out of view is enough.

Choosing a marking system: flags, stars or both

Flags answer "is this in or out" and stars answer "how good is it"; you can use both without conflict. A simple scheme is X for pass one rejects, then stars for a graded pass two. The Lens Lounge describes a three-pass star routine in which one star means acceptable sharpness, two means good composition, lighting and expression, and three means best of a similar group; before deleting, the author sorts the collection by rating and removes the lower-rated images. That is one photographer's published routine, not a standard. As a judgement, a flag-only scheme is simpler, while a star scheme gives you a ranking if a client later asks for a smaller set. Pick one before you start, because switching halfway through a gallery is how frames get lost.

Auto-advance. Lightroom can move to the next photo after you apply a mark, saving a keystroke per frame. The Lens Lounge names one key in its steps and another in its tips (conflicting sources within one page), so check Adobe's help for your version.

Collections versus folders. The same guide works from a collection built from the import folder and deletes from the folder only after editing. A collection holds the picks apart from the originals, which suits a "do not delete until delivered" rule.

Previews and speed

How fast Lightroom feels while culling depends largely on the preview it is showing. Standard previews, 1:1 previews and Smart Previews trade build time against how quickly each frame appears and how well you can judge focus. The Lens Lounge suggests building 1:1 previews on import so zoomed focus checks are quick; whether that pays off depends on your import time and storage, which the guide does not measure. Which is fastest on your catalog and drive is something to measure on your own machine; no timing is published here. What to confirm in Adobe's help: the preview size options in your version, whether Smart Previews are enough to judge focus on your screen, and what happens to flags when the original files are offline.

Assisted Culling

Adobe's Assisted Culling page (published 24 August 2026) describes AI that detects issues in your photos and sorts them into Selects and Rejects for you to review. Per that page:

• It is available in both Lightroom and Lightroom Classic. In Classic, the page places its panels on the right side of the Library module.
• Select criteria are subject sharpness, eye sharpness (each with a 0 to 100 threshold slider, default 50) and eyes open, with an option to reject images where eyes cannot be determined. Reject criteria are documents and receipts, misfires and exposure issues.- You can review the rejects, override any you want to keep, and then apply a flag, star rating or colour label, add photos to an album, or remove rejects.

Not stated on the page: a release date, a version number or a plan requirement. Treat those as unconfirmed and check the Adobe documentation and your plan before relying on it. Whether the analysis runs locally or in the cloud: not found in sources reviewed. For a view of how it fits the 2026 changes, see Lightroom AI features in 2026; for how it stacks against paid tools, see Lightroom vs paid cullers.

A sensible way to use it: run it on a gallery you have already culled by hand, and count the delivered frames it rejects before you trust it with a fresh one. Because the sharpness sliders set a threshold, raising it rejects more images, and your rejects pass is where the cost shows.

Common problems

• Flags do not appear in another app. Lightroom keeps data in its catalog, and a second program sees only what is written to sidecar files. Check how your catalog is set to write metadata before relying on flags elsewhere.
• Rejected photos seem to have vanished. A filter is probably hiding them. Clear the filter before assuming anything was deleted.
• Survey is too crowded to judge. Narrow to one moment at a time; Survey suits a handful of frames, not a section of the day.
• Second shooter frames are out of order. Sort by capture time and fix clock offsets first; see how to cull wedding photos.
• Assisted Culling rejects frames you wanted. Treat the sliders as thresholds you can lower, or run it as a second opinion on a gallery you already culled.

When to hand off to a dedicated tool

Lightroom's own marks are enough if culling is not your bottleneck. If it is, a dedicated culler can take the first pass and send ratings back. For example, Aftershoot says its edits are written to image XMP files and tells you to use Metadata, Read Metadata from Files in Lightroom if they do not appear (Aftershoot support); confirm that menu name in Adobe's help. Narrative Select is another option. If you want to try before paying, see free and trial options.

Check this in your trial

1. Do flags set in Lightroom survive a restart and show in a second catalog or app that reads the files?
2. Does Assisted Culling's analysis need a setting turned on, and where is it in your version?
3. Does it run on your plan and your hardware without extra downloads?
4. Run it on a delivered gallery: how many delivered frames did it mark as rejects?
5. If you use a second tool, does Lightroom read its ratings back after you refresh metadata?

Original test pending: on a licensed wedding gallery per our method, we would time Lightroom's preview types and Assisted Culling against a human cull, and report keepers found and false rejects.
