I can find examples of shot noise in monochrome images, but I can't find any examples in color images. What does shot noise in color images look like?

    It looks pretty much the same: random. ;) – jrista Apr 5 '12 at 0:19

Exactly the same. Both CCD and CMOS sensors - with the exception of Foveon sensors - are achromatic. Color is created by an array of color filters in front of the sensor, so the shot-noise is the same, only you tint each pixel Red, Green or Blue. A few rare cameras also use Emerald tint and some leave one sub-pixel achromatic.

  • Can you provide examples, assuming a Bayer array? – bwDraco Apr 5 '12 at 2:57
  • @DragonLord - Look at any ISO-noise test. There is your example. – Fake Name Apr 5 '12 at 7:40
  • Look at an ISO noise test as long as Noise-Reduction was turned off, which is not possible on each camera. Here is an older one from a Nikon D3: blog.neocamera.com/?p=244 – Itai Apr 5 '12 at 13:26
