When I was younger (but not by much), I really wanted to be an astronaut. I never thought about the possibility of being an astronaut and a photographer. Here's a manual made for NASA astronauts in 1984 on using the Hasselblad 500 EL/M to make great photos. In space. Aside from how to operate the camera, it also outlines basic technique like depth of field, composition, exposure, etc. But in space. Cool stuff.
