Lightroom Classic June 2026 Update: Duplicate Detection and 9 More Features Worth Knowing

Adobe has rolled out another major update to Lightroom Classic, and while it packs ten notable additions, one feature finally answers a request photographers have been making for years: duplicate detection.

Beyond that headline, the update brings improved AI masking, faster Denoise performance, keyword syncing across the Lightroom ecosystem, an upgraded Assisted Culling, and a brand-new background activity manager. Here is a closer look at what is new and how each feature fits into a real working photographer''s day.

How to update Lightroom Classic

Before exploring the new tools, make sure you are running the latest version. Open the Creative Cloud desktop app, head to the Apps section, and choose Check for Updates — this forces Creative Cloud to ping Adobe and pull anything that has not appeared yet. When Lightroom Classic shows up in the list, click Update.

On first launch you will be prompted to upgrade your catalog. Lightroom automatically stores a backup of your previous catalog in a ZIP archive, so you can roll back if you ever need to. The upgrade itself is quick and uneventful.

Finally: duplicate detection

This is the standout feature. The new Duplicate Detection tool scans your catalog and identifies duplicate or visually similar images — and it is not just matching filenames. Lightroom uses AI to analyze the actual image content, so it can flag matches even when the file names are completely different.

When duplicates are found, Lightroom automatically organizes them into stacks. Click into a stack and you can review the matches side by side. Simple on the surface — but there are a few things to understand before you start deleting.

Remove from Lightroom vs Delete from Disk

When you act on a duplicate, Lightroom offers two options:

• Remove from Lightroom — clears the image from the catalog only. The file stays safely on your hard drive.
• Delete from Disk — permanently removes the file from your computer.

The catch is that Lightroom does not immediately surface the file path while you are reviewing duplicates. Before deleting anything, right-click and choose Show in Finder (Mac) or Show in Explorer (Windows) to see exactly where the file lives.

You may discover that what looks like a duplicate is actually serving a different purpose — one copy in your master archive, another in a presentation folder, client proofs, or a mobile-export library. Deleting blindly in those cases can break a workflow you set up on purpose.

Tip: Always verify the file location before deleting. Two identical images may be stored in different folders for very different reasons.

A smarter way to review duplicates

One trick makes Duplicate Detection much more usable: show the folder name directly in Grid View.

1. Open View > View Options.
2. Turn on extras and choose Compact Cells.
3. Under the Compact Cells extras, choose the Folder display.
4. Enable Top Label so the folder appears over the thumbnail.

Back in Duplicate View, you will now see the immediate folder name under each image (unfortunately not the full path). That single piece of context can prevent expensive mistakes.

New background activity manager

Lightroom Classic now has a dedicated panel for background processes. Click the new status icon and you can see what is running — Duplicate Detection, Face Detection, Address Lookup, Assisted Culling, and more.

Each task can be paused individually, which is genuinely useful when you are editing a heavy job or working on an older machine. Instead of nuking everything, you can selectively pause the tasks that are not important right now.

Select Subject gets a major upgrade

The masking improvements in this release are bigger than they look. To see it for yourself, create two masks on the same image — one with Select Person, one with Select Subject — then switch the overlay to White on Black and zoom into hair, fur, or feathers.

The new Select Subject mask captures fine edge detail dramatically better. Hair strands, feather textures, and other delicate areas come through far more accurately, while Select Person still produces the softer edges we are used to. In a lot of situations, Select Subject now delivers results that previously needed manual refinement.

Tip: For hair, fur, or feathers, try Select Subject before Select Person — the edges are noticeably cleaner.

Faster AI Denoise on Apple Silicon

If you are on an Apple Silicon Mac, AI Denoise is now significantly faster. High-ISO RAW files that used to require a long wait now process much more quickly, and dialing in the Denoise amount feels far more responsive. For event, wildlife, concert, and low-light shooters, this single upgrade can save real time. Note: it only works on RAW files.

Assisted Culling leaves beta

Assisted Culling has shed its Early Access label. The headline improvement is group-photo detection: Lightroom now evaluates each person inside a group rather than treating the whole frame as one subject, so it more accurately flags closed eyes and missed focus. For portrait, wedding, and event photographers, this finally makes Assisted Culling practical.

New AI filters in metadata search

An easy-to-miss addition lives in the Filter Bar (press \, then choose Metadata). You will find new AI-related filters:

• AI Edits
• Generative AI Edits
• AI Updates Required
• AI Edit Requiring Updates

For large catalogs full of AI-based removals, masks, and enhancements, this is a much better way to keep tabs on where AI has been used — and quickly review those edits.

Keyword syncing finally arrives

If you bounce between Lightroom Classic and Lightroom Cloud, this update solves a long-standing pain point: keywords can now sync between both ecosystems. Open Preferences, go to the Lightroom Sync section, and enable the new Keyword Syncing option. Your keywords now follow you between desktop and mobile, making catalog organization far more consistent.

Improved brush performance

Brush responsiveness has been worked on too — useful if you do a lot of dodging and burning with masks. On higher-end systems the difference may be subtle since performance was already solid, but many users should notice smoother strokes and less lag. Worth testing if brushwork has felt sluggish for you in past versions.

New Canon tethering engine

A quieter but meaningful change: Adobe has rebuilt its tethering system to use its own engine instead of leaning entirely on Canon''s API. That gives Adobe more control over future development, with potential upside in faster camera support, quicker bug fixes, better reliability, and more frequent feature updates. It launches with Canon, but it is easy to picture this approach expanding to more manufacturers.

Final thoughts

This update delivers improvements across the board, but Duplicate Detection is the headline — being able to surface duplicate and visually similar images automatically is something photographers have wanted for years. Beyond that, the masking gains, faster Denoise, keyword syncing, and improved Assisted Culling all add up to meaningful workflow upgrades rather than flashy extras.

Adobe is clearly focused on making Lightroom faster, smarter, and more efficient for working photographers — and that is exactly the direction many of us have been hoping for.
