Colour noise on Canon 30D

[sigis]

Hi to all,

I'm new member in this forum.
Have question to all Canon 30D users. Have you same problem with noise (looks like color grain) in almost all pictures on 30D, even when ISO100? This is my new camera, upgraded from 350D, and I see so big diference in noises, especialy in dark areas on a photos. I use 17-40L USM on 30D. Have 15 days to send back camera to seller, if is something wrong in it. Can somebody help me to do further decision? And apologise for my incorect english, if is... :)

Some colour noise will always be there, especially in "grey" areas. If you look hard enough and at 100% pixel size, that is.

If you want us to put your heart at ease about it, post some 100% crop examples. But I am almost totally sure your 30D is fine.

Is any one way to attach pictures in original size?

No, and for good reason. You do not want to visit a webpage that wants to open a few MB of pictures...

So, that is why we asked for you to crop a photo. Just cut a part out that shows what you mean, and post that part of the photo. A 100% crop, as it is called, because you see the full pixels.
