It's a great day for Adobe-using photographers. The imaging software company has just released a large update to Adobe Camera RAW, the system that handles raw image processing for programs like Adobe Photoshop CS2 and . Raw files are the unprocessed data recorded by digital cameras' sensors. Because they're uncompressed, they're free of any JPEG compression artifacts and produce the clearest, most accurate pictures. However, every camera sensor records images slightly differently, so support for each camera must be coded separately into raw-processing programs. Adobe's update includes support for 13 new cameras, including the Canon EOS Rebel XTi and the , two of the most popular new cameras on the market today.
