Adobe Photoshop Lightroom 1.1 is available now as a free upgrade for existing users.

The new version adds new functions, such as a flexible image-management system for multi-computer workflows, improved noise reduction and sharpening, and RAW file support for 13 additional digital cameras from leading manufacturers including Canon, Nikon, Olympus, and Phase One.

"Although the beta period has ended, we are happy to say that Photoshop Lightroom continues to incorporate user feedback with this latest update," says Tom Hogarty, product manager for Photoshop Lightroom.

Like Apple's Aperture application, Adobe's Lightroom software lets photographers import, manage and present large volumes of digital photographs.

Lightroom uses Adobe Photoshop Camera Raw technology and also supports JPEG and TIFF file formats.

A catalogue-based image-management system means photographers now can move images and information quickly between their computers.
