I’m quite new to Photoshop. After dabbling with PSE4 (it came free with my scanner), for a while I’ve purchased PSE6 and am spending many hours becoming familiar with it. I’m principally working with photographs I’ve taken with my Canon Digital Rebel camera.
Three questions:
Relating to dimensions and resolution. When I save a Raw file, import it into PSE6, and open it, Photoshop says its dimensions are 14.4 x 9.6 inches, and its resolution is 240 ppi. When I save a jpg file, Photoshop says its dimensions are 48 x 32 inches and its resolution is 72 ppi. Where do these dimension and resolution values come from? Can they be controlled?
The Adobe Help for "Crop an Image" says "If you use a preset size, the resolution changes to fit the preset." Indeed, I see that the resolution changes when I crop to a preset size. But, what does Adobe mean by "to fit the preset"?
The Canon specifications state that the camera saves 12-bit images. When I import Raw files into PSE6, I see 8-bit images. What’s happening to the other four bits? Are thery simply discarded?
A comment. PSE6 includes an inadequate Help file. The file includes useful information about many topics, but is far from complete. Adobe’s on-line Help fills in some of the gaps, but leaves many topics uncovered. I’ve spent many hours hunting on the web for answers to specific questions I have– here and there I find some answers and hints, but it’s a frustrating process.
