Lightroom 4.1 Now Available on Adobe Labs

It’s only 3 weeks since Adobe released Lightroom 4.0, yet here we are with a version 4.1 Release Candidate. Why so soon?

Well, shortly after Lightroom 4.0 was released it became apparent that there were a few serious bugs which severely impacted on performance. There was also an issue that caused Point Curve adjustments from Lightroom 3 to not show after the catalog was updated for compatibility with Lightroom.

Lightroom 4.1RC also includes support for the recently introduced Canon 5D MkIII Digital SLR.

The full list of bug fixes included with Lightroom 4.1RC is as follows:

  • Point Curve adjustments made in Lightroom 3 and before have been restored.
  • Lightroom 4 did not properly open external applications when using the “Edit In” functionality.
  • Addressed performance issues in Lightroom 4, particularly when loading GPS track logs, using a secondary monitor, and the controls within the Develop module.
  • Ability to update DNG previews and metadata for more than 100 photos has been restored.
  • This update allows for improved viewing of subfolders and stacks in folders with a large number of photos.
  • It was possible that a layout of a saved book could be lost after quitting Lightroom 4.

Lightroom 4.1 RC can be downloaded from Adobe Labs. Adobe also want  feedback on your experience with the Lightroom 4.1 Release Candidate. Therefore, a dedicated feedback portal has been provided.


If you’re still using Lightroom 3.6 and need support for Canon 5D MkIII then convert your files to DNG using the free DNG 6.7 Converter

Photoshop CS5 or 5.5 users should download Camera Raw 6.7 for native support of Canon 5D MkIII files.
