hear hear on the Ansel Adams book, I have his photo instruction books he authored, and let me tell you he really goes into detail.
I used to hate the last days of printing in labs, the amount of assumtions that their printing software did to the pictures, so, I like way more today's world where you decide the amount of editing and in the end, the final outcome of the photo.
I do like how with the newer SLRs I spend less time sharpening, and reducing noise, and now spend time on contrast, local area adjustments (dodging/burning), so that I would say the amount of editing has been reduced.
That said, on slow cold days, very enjoyable to experiment and push the boundaries, that is how one learns. No loss, its DIGITAL! just pixels in memory.
