Virtually, all digital cameras inherently create unwanted
imperfections known as noise. The amount or type of noise in
an image typically depends on the quality and type of imaging sensor with
which it was created.
Contrast (Luminance) Noise and Color (Chrominance)
Noise can be individually present in an image or might be seen
in the same image. Fast or high ISO speeds and low light levels
can add noise to images, while some images might exhibit high levels of
JPEG artifacts.
Dfine
2.0 gives you unprecedented control over exactly how much and where to
apply noise reduction. This makes it ultra-easy to eliminate noise in
your images while maintaining detail and sharpness, thus improving the
quality of every digital photo you take. Dfine 2.0 is designed to
prevent the loss of detail other noise reduction tools often introduce.
