The release candidate (RC) versions of Lightroom 3.4 and Adobe Camera Raw 6.4 are now available at Adobe Labs. RC versions have been poked and prodded by beta testers and represent the step before a final release, generally within about two weeks. They're betas, but stable betas.
The LR3.4 RC adds support for seven cameras, including Canon's Rebel T3 and T3i models. It also adds 13 lens profiles for Canon, Leica and Nikon models.
Among the seven bugs fixed:
- A magenta cast that appeared in some Nikon D7000 images when making multiple exposures in the raw format.
- An occasional metadata problem that appeared after editing a Lightroom image with the Photoshop.com online program.
