I am shooting around my desk at ISO 6400. Please help me identify the ISO noise.

HFB, the "noise" refers to the speckled appearance in the image, it shows up especially strong in the areas that have large solids such as on the computer case. Although it can be removed with filtering software, when it is to the extreme like in this photo, you will also lose some detail. I shoot with the T3i and have learned to never go beyond ISO 800 unless that is the ONLY way to get the shot or else the shot is going to have excess noise to deal with, try to keep your ISO around 400 or less, 6400 is pushing it way too far on this camera, even with good lighting.

I was looking for much worse than I am seeing. It is about like film grain at 6400 with ,to me, a lot of blowup. Thank you for your information. It does not appear to be as noticeable in white areas.

There is no detail in the white areas, so there will be no noise. The darker the area the more the noise shows up.

If this is as bad as it gets I am OK with it.
Thank you again for sharing your knowledge and experience.

On this example, agreed. You can see some white specks of color in the dark areas to the left of the lens. You can also see total black spots in the same grey area. You need to view 100% or 200% on the downloaded file (aka pixel peep). At 6400 ISO that is very good, particularly as a starting point for slight additional noise reduction.as bad as it gets

Thank you for your comments. I am first a film camera person. I got theT3i to help me get better as a photographer. I can get instant feedback. But after looking at the images I have gotten so far I understand why digital is so popular. A little PP has made some improvement but I am very pleased with what the camera can do. It will beat my AE1. I still think medium format film will look as good. Printing starts soon.

Look closely at the darker areas, the computer frong and that dark area to the left. If you blow that up in an editing program the tiny white specs will be visible.

Yes, not too bad for B/W but if you still have the original in color look at it, all those little noise specks will be contrasting colors to the background they are on and throw the correct color off quite a bit, the whole image will have lots of purple and green noise in it.
