AKVIS Noise Buster focuses on correcting both luminance noise and color noise with separate control settings for each of these categories. One feature in the application that is particularly nice is the histogram that detects and shows, with a single glance, both luminance and color noise levels in the digital photograph you are editing. This is very helpful feedback for those who want to depend on more than just the naked eye when making adjustments.
When dealing with larger images, processing time can become quite slow. This is to be expected, to some degree, because of the modifications that are being made, and the time taken to complete the noise removal process seems very much in line with other applications of this type. Fortunately, you can make and preview several changes and then apply them all at once. This way, you can save all of your waiting time until the end of your photo editing rather than sit and endure after each minor change.
How does the program fare when it actually comes to removing noise? For common minor noise problems, Noise Buster does an excellent job. However, the application did not seem to perform as well on images with major noise issues or on ones riddled with compression artifacts. If you have to deal with these problems often, you may want to seek out another application, such as Topaz DeNoise, for your editing projects.
