The gold standard for noise reduction in images is Noise Ninja. Aperture’s noise reduction tools are not the greatest, so it is pretty exciting to learn that Picture Code has released an Aperture Plug-in. Just one more thing to add to my list to buy. They have profiles for individual camera’s that enables the plug-in to get great results without a lot of user input after selecting a profile. Check out the before/after page, the images taken with a D70 (I have a D40) are very good. It would enable me to feel better about shooting at 1600 ISO inside.
