The National Geographic is showcasing a few pictures taken from the International Space Station. Usually the pictures take from space are for scientific purposes, and they just happen to be beautiful. In this case they just went for the beauty. It poses an interesting and novel composition problem. What times of day? How to workin the weather? Framing? Angle (straight down or toward the horizon)? Etc. Once space tourism become more common, it will be interesting to see how the art of photonauts evolve, and how old ideas are revisited with the absence of gravity.
