Why don't you use high ISO's for long exposure shots?



  Works...kind of...
Because you'll be blinded when you upload the shot to your computer. :dapprove:

Not bad noise handling by my camera though. :cool:
 
  Cupra
30 seconds at 1600 and you still have a clean image. Any post processing done to remove noise? Does it look that nice at 100%? ;)

Well done? You obviously didn't understand the reason behind the thread. ;)

You're meant to use a low ISO so that the exposure doesn't blow out.

I used 1600 by accident, but never realised how good the noise handling is on my 20D.
 
nothing to do with ISO, thats just bad exposure. changing the iso will just adjust the shutter speed (in av mode) or increase aperture (in tv mode)
depending on the sensitivity of the ISO.

the way to change the exposure would be to adjust the exposure compensation to let less light in

I was using Bulb mode in full manual, dude. I like to have full control, so I never use Av/Tv.

Actually, the first shot wasn't bulb.

Top picture was a 30 second exposure, second was 1 minute 30 seconds.
