Adobe has released Photoshop Lightroom 2.5 and Camera Raw 5.5, updates to its photography and digital photo decoding software, respectively. Both are available for download through Adobe's Web site or through the update mechanisms in Photoshop CS4 and Lightroom 2.
Adobe's Tom Hogarty posted the information to the Adobe Blogs. The 'final' release of Camera Raw 5.5 comes following the release of a 'final candidate' version for testing.
Both releases update support for new digital camera models. Newly supported cameras include Nikon's D300s and D3000, Olympus E-P1 and Panasonic DMC-GF1 and DMC-FZ35 cameras. Adobe notes that in Europe and Japan, the DMC-FZ35 is sold as the DMC-FZ38, and has metadata differences that won't be supported until the next revision.
Adobe notes an important under the hood change: Both software updates correct demosaic algorithms for cameras that use Bayer sensors with "unequal green response." This includes models from Olympus, Panasonic, and Sony. The change provides "only a subtle visual improvement to the processing of those raw files."
