Don Pettit, famed International Space Station photographer, gives an interesting talk at Luminance 2012 about the opportunities and difficulties of shooting aboard a space station.
Expedition 31 Flight Engineer Don Pettit relayed some information about photographic techniques used to achieve the images: “My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.”
