Astronaut Leroy Chiao's Space Blog-Corrientes, Argentina

This is a good example of what is possible using space-based astronaut photography.

This is a very striking photo. It was taken using a hand-held 800mm lens. With the longer lenses, one must develop the technique of matching the earth's rotation during the composition of the photo. We shoot at 1/500 s, aperture priority, but even so, one must compensate to prevent smearing of the image. Adequate lighting and atmospheric conditions are also factors. In this case, it all came together. You can see the sunglint on the river, which reveals very sharply, the flow and subsurface flow patterns of the water. The bridge is well-defined as are the individual streets of the city. This is a good example of what is possible using space-based astronaut photography.
