Some cameras produce more digital noise than others. Digital noise can make a picture look grainy (similar to high ISO film prints), can produce static-like patterns (random or banded), and can give a picture a dusty or muddy look. Several off the shelf software packages contain "quick fixes" for noise patterns, but generally do a poor job at it, and noticeably degrade the image quality while doing so. Other solutions, although often effective, are patterned around rather complicated and time consuming procedures. But Quantum Mechanic Pro, an Adobe Photoshop based "plug-in", is easy to use, fast, and efficient. I've used the original version of Quantum Mechanic since early 1999. It was a solid investment, and has fixed countless noise problems in pictures from a wide range of cameras. In many cases, high ISO pictures that would have been otherwise too noisy for practical use have been transformed into showcase samples. (Examples in this website: Kodak DCS 620 Night Drags & Fuji S1 Pro State Fair Photo Display.) Quantum Mechanic Pro is a significant upgrade and refinement to the original version. I consider it an absolute "must have" for the digital professional or serious enthusiast.

I looks pretty good the way it came out of the camera, but it can be made significantly cleaner looking with a little help from Quantum Mechanic Pro software.
