Noise on Canon 350d/Rebel XT @ ISO800

I left the settings to ISO800 by mistake and thought at least some use for the shot would be to let people see the noise.

I have to stress that this is ISO800 and that the camera performs 100 times better and very cleanly at the usual ISO100, ISO200.

24-105 @ 40mm

No compression on this image, so it's not jpeg artifacts. It wasn't cropped or resized either, it's 800px wide straight from the original.1

looks about right.

I would have expected even more noise from a 350 D. looks OK for ISO800.

I should do an actual series through the range
