Description
The vendor makes noise reduction an easy-to-use, four-step process with Dfine, a package
that lets you correct luminance noise, chrominance noise, and JPEG artifacts. It has
fully professional features such as noise analysis, with optimization using camera-specific
profiles. With these tools you can control the relationships between detail, noise, and
color, thereby maximizing the quality of the image.
