Wow. Thank you for the replies, Neil, Ernst, and Bill. I do understand gamut, and don't offhand remember the difference between the two major rendering intents, but for what it's worth, I have always used relative colorimetric with black point compensation (I did know the difference at the time I made the choice for relative colorimetric). What I could probably figure out if I wrapped my head around it, but you may know right off the top, Ernst, is whether that choice will tend to give me more or fewer issues when I make a change. And actually, I don't do that many reprints to worry me unduly. I can do any edits that are needed. The comments about the edits, Ernst and Bill, helped tremendously, and gave me less to worry about. Now I know what to look for. Any increased gamut I can appreciate and enjoy and make the necessary adjustments. I enjoy doing landscapes, and any additional range in the blues would be quite nice.
Bill, I enjoyed your comment about the refrigerator. I finally, in my 60's, have a refrigerator I love. But I love my printers at least as much (no, undoubtedly more). The thing for me about photography is that it is a multi-part creation, and I love each of the parts -- the capture with the camera, the editing in Photoshop (and I've tried to learn CaptureOne), and the print. What a joy it all is! -- Barbara
