http://eol.jsc.nasa.gov/Videos/CrewEarthObservationsVideos/ [Broken] I saw one of these videos and they seem pretty badass. However, I was wondering, does anyone have any idea of what kind of exposure you need for those kinda videos? I'd be speechless if the exposures were the usual fraction of a second exposures you normally do and just compiles together to run at the 24-30fps. I imagine they may be a few seconds exposure, but I don't know :) DISCUSS!!!!
