A few weeks ago, I was told by a friend about a plug-in called AKVIS Noise Buster that could help me with my picture noise problems.

For my work I always start from photos I take by myself and I also do a lot of scans. My main problem is to improve the photo and scan quality first because all the scanned pictures have always a lot of noise especially those that come from prints. Photos taken under bad light conditions also have a lot of noise.

The only solution I had in Photoshop was to Gaussian blur and then to Unsharp Mask my source images. I was also struggling with PS noise filter to remove remaining noise. But the main point with all these tools is that whatever you try, you always loose picture sharpness and details in the end.

I then tried AKVIS Noise Buster and on my first attempt, I was immediately amazed. It does a great job of smoothing my images without losing sharpness. For example, in a close-up view of an image where you can see all of the skin imperfections, AKVIS Noise Buster transforms it to an image where the subject has smooth young skin while preserving the sharpness of the eyes, lips, and other details.


Sometimes you get a very bad JPEG image file.

At first sight it looks not so bad, but if you zoom a little, you'll see the typically square-pixellated design which can be found on bad JPEG's.
