Sharpening and reducing noise in raw camera files

You can sharpen raw camera files to enhance image edges.

Raw camera files may contain luminous (grayscale) and color (chroma) noise that is especially obvious in the darker areas of an image. Luminous noise appears as a “white snow” effect; color noise appears as random pixels of different colors scattered against image areas. You can reduce noise in raw camera files to improve image quality.
