Looking at a shot of Vincent Laforet's from the February 2008 National Geographic. The image is shot from a helicopter, looking down on an Arizona pool. It's flat. No noticeable curvature.
You can see examples of this at Vincent Laforet's website under Portfolio -> Air (specifically images 2 and 5).
How was this look achieved? Frame within a frame on a telephoto and crop to avoid curvature? Post processing?
This look is popular in National Geographic's "Visions of Earth" magazine section. Images aren't always shot from a helicopter.
