Dark Frame Test

on

Brand new Canon EOS 450D (modified)

 This is a crop of a single 10s dark frame, taken without lens and with the camera body cap on.

 If you follow the hyperlink to the original size (4272x2848) and adjust to 100% pixel size you can identify several  hundreds of yellow, blue and white points which I think are dead and hot pixels.

Similar tests at 5s, 20s and other exposure times have shown identical results.
