Does my 5D3 look extra noisy to you?

This is something I've been noticing more lately, that my 5D3 seems particularly noisy. I've not sent it in to Canon yet. I always read reviews that as far as noise goes, it's barely noticeable up to about 3200 and still usable up to about 6000-10000 (depending on the review). I don't feel that's the case with mine. At 1200-1600 I feel like it's very grainy when zooming in on the picture. Here's an example from this morning. SOOC, about a 100% crop. 5D3 with 50mm 1.8 mark 1, 1/125, f5.6, ISO 250.

Heya,

You're looking at a 1:1 crop of an under-exposed area at a non-native ISO value. Looks like I would expect it to.

Looking at your Flickr, your other 5D3 images even at ISO above 1600 look clean.

Did something happen? Or are you just pixel peeping?

Very best,

Thanks, most likely the second, but I'm not sure. The last two gigs I had were a wedding outside on the rainiest day possible, and a proposal indoors in a dark church where I couldn't set up enough lights because of discretion. I've been looking at those pictures non stop so maybe my mind has forgotten what correct lighting and exposure look like haha.

Looks fine to me, mine is fairly bad in general - I have my Noise reduction on at 50% always.

You wildly lifted the shadow areas. This is the expected result.

Remember one thing....

Taking a result from a camera and raising the shadows isn't the same thing as raising your ISO before the shot. Using ISO in camera will provide you an analog amplification which is better than the mathematical amplification you are doing after the fact.

So in the underexposed areas of a file, when you run sliders up to bring out the shadows, you are simply multiplying each pixel in that shadow area by the slider values, bringing up the floor noise that Canon cameras are known to have. If you had raised your exposure so that the brightest area just hit the right side of the histogram, then the shadowed buildings might pull up a little better. Even better, just do a bracketed shot and merge after the fact, or use the HDR function on the 5D3, it would work very well for this type of shot.
