    30D owners

    Originally I was pretty happy with my 30Ds high ISO performance . . . and then I started noticing in real life applications it wasn't so stellar.

    I took some some test images again to see about how exposure effected Noise on my 30D and again, I wasn't too happy with its ISO performance. at all levels. . .

    Here is the senario - here it is at ISO 3200 -



    First start at the P in Pringles and work your way left. . . do you notice the banding there? Maybe thats normal.

    Ok now I'm going to show you a blow up of the area to the left of the can of pringles. . . its something I've been noticing as well. . . I have noise. . . then I have these what I call white specks, do you see what I'm talking about?



    ISO 3200 is the most pronounced of all ISO settings, but these results are present in lower ISOs as well. . . Here is a crop similar to the one above at ISO 1600 - you can see not as pronounced but still present - Those "White specks"



    My question is this. . . does your 30D have banding to the same degree mine does and does your 30D have those white specks. . .

    I appreciate you taking the time to look into this. . . Maybe I'm being paranoid. . . but it feel these noise levels are high and the specks ought to be abnormal as well. . . ???

    Not sure about the white specks - I rarely shoot at 3200, and even more rarely view images at 100%. Aside from the specks, that looks darned good. I mean it's 3200! The shadow areas will always show more noise, but the crops you posted are pretty dang clean.

    If you think that is disappointing for ISO 3200... be very very glad you did not opt for a Nikon D200! The difference is HUGE.

    To me this looks very good. The only cameras that will do better are the 5D and 1D series, I think. Nothing else in the market place comes close to what your 30D does... you should see the horrid noise a Leica R9 with digital back produces. (cwphoto mentioned that camera a week or two ago... it really is not pretty what that camera produces above ISO400).

    How long did you expose for? I just now tried a ISO 1600 stot with my 350D, but it is a sunny day and I can't get it very dark, so my shot will have a lot less noise because of the short exposure duration. I do not see the white spec effect in my shot, maybe because of that, and also I did shoot JPEG, so probably the test is also in that respect not consistent with yours.

    And also I didn't have any pringles ... so I just put a bottle of wine there from the country of beautiful brides and grooms, cw's oz-land.

    100% crop, no white-ish "specs".

    Now as RAW, no sharpening or noise reduction, with Canon DPP.
    More noise than in the JPEG, but no white specs.

    100% crop, you can see that the 350D is more noisy now.

    Perhaps pixel peeping produces perception problems? Probably pure paranoia...

    No guys. We've seen this all before. I smell a 5D coming. I don't know how, but he'll figure a way. Maybe he's got someone on the hook for a wedding for 2K CASH.

    Andy, do you mean how it's more pronounced in the shadows to the left? I'm sure you know that good lighting and correct exposure reduces high ISO noise. Therefore, noise will be uneven for shadowy photos.

    I've taken only 2 or 3 ISO 3200 shots so far. Will take a look tonight.
