You can cull a shoot in Lightroom Classic without any other software, and fast, if it is set up for it. Import with Embedded and Sidecar previews so frames appear instantly, cull in the Library module's Loupe view with Caps Lock on so P and X flag a frame and move to the next, settle the close calls in Survey or Compare view, then filter to Flagged and delete the rejects.
Most slow Lightroom culls are slow because of settings, not because Lightroom is a poor culler: full raw previews rendering on every frame, a mouse click to move on, and a filter nobody switched on. Here is the setup and the sequence, with the exact keys.
Which import settings make culling faster?
Open the Import dialog with File > Import Photos and Video (Cmd+Shift+I on a Mac, Ctrl+Shift+I on Windows). In the File Handling panel on the right:
- Build Previews: Embedded & Sidecar. Lightroom shows the JPEG preview your camera already embedded in the raw file, so frames appear immediately. The other options make you wait while Lightroom renders every frame before you can look at it.
- Build Smart Previews: off for a cull at your desk. Turn it on only if you will cull or edit on a laptop away from the drive; smart previews explains the trade.
- Don't Import Suspected Duplicates: on, which saves you culling the same card twice after a second import.
In Apply During Import, add a metadata preset with your copyright and a keyword for the job. You will not be in the mood to do it after the cull.
The one catch with embedded previews: zooming to 100% still forces Lightroom to render from the raw file. That is fine for the handful of frames you check for focus, and a reason not to zoom on every frame.
Should you use flags or stars?
Flags for the cull, stars afterwards. A flag is a binary decision: P for Pick, X for Reject, U to clear it. Stars (keys 1 to 5, 0 to clear) are better saved for a second job, such as marking the five star frames for an album or the sneak peek.
Mixing the two in one pass is how culls stall. Pick one meaning for each tool and write it down if you work with a second shooter or an editor. Colour labels (keys 6 to 9) are free for anything else, such as "needs retouching".
How do you turn on auto advance?
Press Caps Lock, or choose Photo > Auto Advance. With it on, pressing P, X, a number or a colour key applies it and moves straight to the next frame. Without it, every decision costs a second keystroke on the arrow key, which adds up over a thousand frames.
If you prefer to leave Caps Lock alone, hold Shift instead: Shift+P picks and advances, Shift+X rejects and advances, for that one frame.
Set up the screen before you start:
- E for Loupe view, one frame at a time.
- Shift+Tab hides all panels so the frame fills the screen. T hides the toolbar.
- L cycles Lights Out, dimming everything but the photo.
- I cycles the info overlay, useful to see the frame number and capture time.
Then work through with the right arrow, P and X only. Unflagged means you have not decided yet.
How do you compare similar photos?
Group the near-duplicates first. Photo > Stacking > Auto-Stack by Capture Time groups frames shot within a set gap, for example two seconds, into stacks you can expand and collapse with S. That turns a burst of twelve into one decision.
For the decision itself, Lightroom has two views:
- Survey view (N) shows every selected frame side by side. Select the burst in Grid view, press N, and click the small X on the worst frame to drop it from the survey. Keep going until one or two remain, then flag the winner.
- Compare view (C) puts two frames next to each other: the Select on the left and the Candidate on the right. Use the arrow keys to bring in the next candidate. When a candidate wins, click the swap button in the toolbar so it becomes the new Select, and carry on.
Survey is quicker for picking one from six. Compare is better for two frames that differ in one detail, such as a closed eye, because you can zoom both at once with the Link Focus lock on.
How do you show only the picks?
Press the backslash key () in Grid view to show the Library Filter bar, click Attribute, then click the white Pick flag. Only picks remain. Cmd+L (Ctrl+L on Windows) turns filters on and off without losing the setting.
The same filter sits at the top right of the Filmstrip if you prefer it there. Two more filters are useful:
- Unflagged only, to find frames you skipped over.
- Rejected only, for one last look before deleting.
Once the picks are filtered, select them all with Cmd+A (Ctrl+A) and add them to a new collection with Cmd+N (Ctrl+N), ticking Include selected photos. That collection is what you edit and export from, while the folder still holds everything.
How do you delete rejected photos in Lightroom Classic?
Choose Photo > Delete Rejected Photos, or press Cmd+Delete on a Mac (Ctrl+Backspace on Windows). Lightroom selects every rejected frame in the current folder or collection and asks whether to Remove them from the catalog only or Delete from Disk.
Remove keeps the files on the drive but out of Lightroom. Delete from Disk moves them to the system bin. Most wedding and portrait photographers keep rejects until the gallery is delivered and approved, then delete; check your contract for how long you promise to keep originals before you empty anything.
Where does Assisted Culling fit in?
Assisted Culling sits in the Library module and flags likely misses (closed eyes, soft focus, misfires) for you to confirm. Run it as a first pass if you like, then do the manual flag pass above on what is left, because it cannot tell which frame carries the story. How it compares with dedicated tools is in choosing culling software, and the habits that make any cull faster are in five ways to speed up culling.
Before your next shoot, set Embedded & Sidecar as your import default and save the import settings as a preset at the bottom of the Import dialog. Then cull the next job with Caps Lock on and your hand on P, X and the right arrow, and time it against the last one. After the edit, send the picks collection through File > Export. With an export plugin like the one Xposure includes on its Pro plan, the JPEGs land straight in the client's proofing gallery.
