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.”

Not to be confused with a hot tub time machine, the GigaPan Time Machine
enables simultaneous exploration of space
across massive datasets that could not previously be interactively explored at full spatial and temporal resolution. Here
is a short demo of the GigaPan Time Machine website. [more inside]

An article at robgalbraith.com
, a digital photography site, has sparked a fascinating discussion
of the merits of Macs vs. those of PC's, as they apply to digital photography. Actually, the article and discussion aren't terribly interesting, but the fact that the discussion is a mutually beneficial exchange of ideas and opinions and not a take-no-prisoners flamewar, is.

I knew this had to happen eventually. Someone finally developed a digital camera in the form factor of a roll of 35mm film
. That means you can just pop it in your regular ol' film camera, and boom, it's digital.
