I have recently learned two basic Camera Raw tips that are significant for my workflow but that do not, as best I can tell, appear in Jeff Schewe's book "Real World Camera Raw with Adobe Photoshop CS5" or other popular references, such as those by Scott Kelby. Jeff, may I suggest that these tips be added to your next edition?
(1) Opening Camera Raw in Photoshop allows for faster 64-bit processing than opeing Camera Raw from Bridge, which is a 32-bit program. To open Camera Raw in Photoshop, use Command/Control-O or set your preferences so that double-clicking on a raw file does NOT open Camera Raw in Bridge (and therefore by default opens Camera Raw in Photoshop).
(2) If you use Camera Raw's output sharpening, you will want to have the image sized correctly. Set the cropping tool to the size print you desire (8x12 and inches, for instance), and your workflow options to the native resolution and the appropriate PPI for the printer you will be using. Then, crop your image, even if the cropping border corresponds with the uncropped image border. When you save your image with sharpening through Camera Raw, the final image will be in the correct dimensions and PPI for your desired print. For instance, an 8x12 image at 300 ppi will be 2400 x 3600.
