I use many of the tools to retouch my images but one of the great features is its ability to remove noise that is caused by crosstalk between the pixels. All the good and expensive cameras have noise reduction software within their circuitry software. If you have a lower priced camera you can use Gimp and the image processing power of your home computer to make your images look great. The two primary noise filters that I use are Selective Gaussian Blur and Unsharp Mask. The parameters can vary but I will provide the parameters that I use almost exclusively. Load and image in Gimp Right-click the image 1). Select FILTERS -> BLUR -> SELECTIVE GAUSSIAN BLUR... Use these parameters Blur Radius 5.0 Max Delta 10 Click OK Then 2).Select Filters -> Enhance -> UnsharpMask Use these parameters Radius 1.0 Amount 0.3 Threshold 0. Click OK You will see an immediate improvement in image quality. The parameters may need altered to suit your particular camera. These work great for me. Have fun with Gimp it is a great tool for image enhancement. Jay
