Adobe update tests Photoshop CS5 lens correction

One of the headline features of Photoshop CS5 arrives a couple weeks after the software: the ability to automatically correct some lens problems in raw files.

Adobe on Thursday released a beta version of an update to its new Photoshop CS5 software that adds the ability to automatically correct lens problems in raw image files.

The Camera Raw 6.1 update beta uses profiles of several cameras and lenses to automatically fix color problems called chromatic aberration, geometric problems called distortion, and darkened corners called vignetting. In addition, in the raw files, photographers can manually change the perspective of a photo somewhat, for example making the converging lines of a building parallel in a shot taken from the ground looking up.

The update also adds support for raw file formats from several cameras already supported in Photoshop Lightroom 2.7, a sibling product geared specifically for editing and cataloging photos. Those cameras include the Canon Rebel T2i, aka the 550D, the Olympus E-600, the Panasonic G2 and G10, and the Sony Alpha A450. Those cameras, except the Olympus model, were supported in Camera Raw 5.7, but Adobe couldn't build that into Photoshop CS5 because of product release timing matters.

Also in the update are improvements to the raw-image plug-in performance and a fix for a crash that could happen on Macs.

The update ships with only a "handful" of supported lenses, but people can create and share their own using Adobe's Lens Profile Creator utility.
