and bright, making shadows darker and highlights
brighter. Decrease contrast and you bring the shadows
up and the highlights down to make them closer to one
another.
Sharpness: Sharpness can be defined as edge contrast,
that is, the contrast along edges in a photo. When we
increase sharpness, we increase the contrast only
along/near edges in the photo while leaving smooth
areas of the image alone.
Saturate: Color gain means saturation, it is similar to
contrast, however instead of increasing the separation
between shadows and highlights, it increases the
separation between colors.
3DNR (Digital Noise Reduction): DNR is a technique
of removing image noise from a video signal by
applying a digital comb filter. It reduces the noise that
can be found in low light images and makes images
clearer. This type of filter is sometimes confused by
motion, resulting in blur trails.
