A screenshot from the cloud-based photo editor 'Project Nimbus', accidentally leaked by Adobe yesterday. Screenshot: MacGenerations

Adobe announced development of its 'Project Nimbus' cloud-based photo editor last year, but we knew very little about this stripped down 'Lightroom in the Cloud.' Until, that is, yesterday when Adobe accidentally released an internal build of the app to some Creative Cloud users.

French website MacGeneration got their hands on some screenshots that were captured by users before the mistake was spotted and the app was taken down by Adobe.

From what we can tell from the screenshots and MacGeneration's description, the app is a lot like Lightroom Mobile for the iPad. Basic light and color edits, brushes and gradients are all available, and the editing workflow is entirely non-destructive. What sets Nimbus apart is that it's entirely cloud-based: as you edit, your edits and photos are automatically saved to the cloud, and the app comes with 1TB of cloud storage for this very purpose.

Here are a couple more screenshots:

After the app leaked, Adobe released the following statement to Engadget:

We mistakenly shared Project Nimbus with a small group of Adobe Creative Cloud customers. As you will recall from MAX in October 2016, Project Nimbus is next-generation photo editing technology that we have been exploring as part of our Lightroom and Photoshop ecosystems. We cannot share any further details at this time but will keep you posted on future developments.

If you're intrigued by Nimbus, you won't have to wait too long before you can give it a shot. A beta of the app is due out sometime in 2017.
