Haven't mucked around with it much. But have total confidence in its abilities to remove image noise from scanning and digital cameras. There are also tutorials for us amateurs;-)
I found the program to work nicely. Gabi gets cds full of images she took using a 35 mm camera, and I found it works really well for removing the noise from her 35mm pics, while being able to sharpen the nonnoise portions of the image at the same time if necessary. I give it a thumbs up. Also has an advanced mode which I havent tried yet ^ ^
