Yes, of course it would only show up in pictures. Where else would it show?

If you want to see samples, read the reviews.

first, open up the image with PS or other software........ then look for slider or control that shows image at 100% .... from there you can begin pixel peeping and checking out visually noise levels

go to dpreview.com and check out some of their camera reviews...... inside these reviews go to sections that relate to image quality where they show 100% crops of set ups in various controlled conditions .......and of course various ISOs

example below link...... pages 14 thru 18 should give you an idea

http://www.dpreview.com/reviews/canoneos7d/page14.asp

some of these 'inspections' u can do it on your own camera too.... best to use a tripod indoors with maybe a timed or remote trigger to keep the variables down

good luck
