Noise Ninja is a commercial software program which uses a bunch of clever tech to remove noise from grainy images. The program also comes with a useful profile feature which lets you create and store profiles for your particular camera at various ISO settings.
This means that the program will automatically select the optimum settings when you open a photo for processing once it’s read the exif info from the image. Great for fast processing. The product costs $34.95 for the standalone home edition, and there’s a pro version which is apparently the tool of choice for a growing number of sports photographers. For an alternative choice, take a look at the $35.00 PureImage program.
Noise Ninja is the most effective and productive solution for removing noise and grain from digital photographs and scanned film images. It is a must-have tool for anyone shooting in low-light or fast-action situations — including news, sports, wedding, and event coverage — where high ISO photography is required and the resulting noise compromises the image.
