Noise...

    I don't know if i'm looking for problems that do not exist, but I can see noise in all my pix that have large areas of plain colour

    e.g.
    456416333_a7f2171838.jpg

    Click here for large size on flickr.

    Settings on this shot are 24mm, 1/800 sec, F8, ISO 100 using a 30D and a Sigma 24-70 F2.8 lens.

    Should it be this noisy? Or am I seeing things?

    better to crop a bit of the sky, paste it into a new pic and post it at 100% so we can see it properly? I can't see any noise looking at the large version here. But then, the frickin sun is shining on my screen and I can't see much of anything :(

    is that straight from the camera or processed with something from a raw file?

    what does a print look like as web sized images don't represent the quality of an image

    No exif available ?

    what ISO u used ?

    here's a 100% crop. It's been processed from RAW with Canon Digital Photo Pro 2.0. I see there is a 3.0 version of this out now with noise reduction, but should an image have that much noise in the first place at that ISO and shutter speed?

    ISO is 100.

    Did you sharpen it ? If so in dpp was it on the first tab or both tabs ? From what I remember (not at a dpp machine at the mo) if you sharpen a raw on the 2nd tab in dpp it introduces a lot of noise.

    perhaps that was it. I'll take a look again tonight and try a few different things. Thanks
