I just picked up this book Apollo Through the Eyes of the Astronauts from the new books section at my library. It has some very nice photos (from a bunch of amateur photographers who happened to also be professional astronauts) along with comments on the photos from the astronauts themselves.
I really found the comments to be the best. In several cases the astronauts commented on what they were thinking when the took the shot or on how they reacted to it upon seeing it exposed and printed back on earth.
They also managed to take some really stunning shots for guys that were working with no meters and no viewfinders at all using 70mm MF film cameras.
Like this comment from Michael Collins on Apollo 11:
"....Just prior to my taking this photograph, they had departed Tranquility Base using the lower half of their landing craft, Eagle, as a launch platform. The upper half appeared first as a tiny gold insect crawling across the lunar landscape, and then began to take shape as a man-made object, althought its angular shape still seemed strange and awkward to me. Little by little they grew closer, steady, as if on rails, and I thought, "what a beautiful sight," one that had to be recorded. As I reached for my Hasselblad, suddenly the Earth popped up over the horizon, directly behind Eagle.......I realized that for the first time, in one frame, appeared three billion earthlings, two explorers, and one moon."
