I'm a 41 Belgian digital painter, living in Brussels.
I've been working with Photoshop, and other graphic programs, namely Poser and Corel Painter for a few years now.
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.
That's when the AKVIS Noise Buster plug-in can be very helpful.
Click on the and buttons again and you get a more corrected image. Maybe you will find this one is corrected too much.
you see that the correction is good on some parts of the image (the posts and the sign) and too strong on some other parts (trees, grass...).
The solution will be to isolate these parts from one another.
I chose a yellow color for highlighting the unselected area.
But it's up to you to choose another color and to highlight the selected area. Personally I usually try both methods and two or 3 different colors on the same image, depending on the dominant color of the image on which I make a selection. For changing these settings you only have to double-click on the Quick Mask Mode button in the bottom of the toolbox.
