Would someone be kind enought to advise me as to the BEST way to save the HIGHEST resoultion possible to my recent edited raw file once i leave camera raw and bring it into CC? I am JUST NOT quite sure about 8bit 16 bit and 32bit and I want to get the very most from what my camera offered, I am presently using Canon 5 D Mark 2
Photoshop and Camera Raw cannot really create higher resolution. Yes, it's possible to resize images and make them larger, but that doesn't always result in higher quality. The best thing to do is do as much of your processing in Camera Raw as you possibly can. This would include sharpening and noise reduction, highlight and shadow recovery, all the things that camera raw is good at. Then go ahead and open the images in Photoshop in 16-bit mode and do any final touchups that are needed. Working in 16-bit mode is a good choice because it will help to eliminate banding and other problems that can occur under certain situations. Other than that, just don't worry about it. Enjoy what you have and explore to find out what works for you.
Jeff Schewe talked about upresing with ACR in an excellent article he wrote back in 2007. It's old, but too good not to read
He discussed it in a recent thread on the Photoshop forum, and the conclusion is that the new Preserve details option in CC is the way to go now.
