You own 450D, hmmmm...
So, you're saying that between the two giant manufacturers there is a modest difference with the noise in low light still images?:scratch:
I am not sure what you are trying to say.
Are you asking for my opinion or stating that I do not have a valid opinion as I own a 450D (and a 20D if you looked at my signature)?
It is just a fact, nikon handle noise much better than canon.
Watch the video links posted earlier and you will see the difference.
as I stated though, I have developed my own method to reduce nois, but it is not efficient to do it to all my images, therfore, the less noise in the original image,the better.
