Adobe's cloud-catalog photo editor. Lightroom.exe is the process. It is not Photoshop and it is not Lightroom Classic.

What you need to know

This Lightroom is the cloud catalog. Classic is the older desktop catalog.

Cloud Lightroom syncs a library through Creative Cloud. Lightroom Classic keeps a local .lrcat file. Photoshop is a pixel compositor. Both can show Lightroom.exe. The install folder tells them apart.

What is it?: Cloud catalog photo editor
Same as Classic?: No. Classic is the local catalog
Same as Photoshop?: No. Photoshop is a pixel editor

Feex says

If the photos live in the cloud library, this is Lightroom, not Lightroom Classic and not Photoshop. I would not treat a missing catalog folder as a broken camera driver.

What is Adobe Lightroom?

Adobe Lightroom is the cloud-catalog photo app. Originals sync through an Adobe account. Lightroom.exe can also belong to Classic. The folder name tells them apart.

If you have never used it

This article is the cloud Lightroom app: a library that syncs through Creative Cloud. Lightroom Classic is the older desktop catalog with a local .lrcat file. Photoshop is a pixel editor, not a catalog. Read the Start menu: Adobe Lightroom vs Adobe Lightroom Classic. Install from Creative Cloud, not a "Lightroom free" host.

What is it used for?

Cloud photo library

Import and browse a library that syncs to phones. Classic keeps a local catalog instead.

Raw develop

Exposure and masking on a camera file. Jump to Photoshop when you need pixel layers.

Presets and share

Apply a develop preset and export JPEG. This is not the Windows Photos album.

Who is it for?

Photographers who want one library on a PC and a phone
Photography plan users who also have Photoshop
Anyone who installed Classic and expected cloud albums

Current status

Actively developed. Adobe still sells Lightroom and Lightroom Classic as two products. This article is the cloud desktop app.

How old is it?

Adobe shipped Lightroom in 2007 as a desktop catalog. In 2017 the name split: Lightroom Classic kept the local catalog, and Lightroom (once Lightroom CC) became the cloud library. A 2007-2016 Lightroom box is the Classic ancestor, not this cloud app.

Installed processes

File formats

Common problems

Installed Classic by habit

A local .lrcat file is Lightroom Classic. Cloud albums are this Lightroom. They do not share one catalog.

Sync paused

Cloud originals need Adobe account storage. That is not a camera driver failure.

Getting unstuck

Read the Start menu name

Adobe Lightroom vs Adobe Lightroom Classic. Open file location if the names look identical.

Check Creative Cloud storage

A full quota looks like a mysterious import stall.

Do not migrate by renaming folders

Copying a .lrcat into the cloud app does not convert it. Use Adobe's documented move.

Alternatives

Lightroom Classic is the local-catalog sibling. darktable, RawTherapee, and Capture One overlap for raw develop. Photoshop is the pixel editor for composites.
