Step Five: Adjust Photo Restoration Options
The second set of controls available will determine how much restoration is needed on the photo, from noise reduction to artifact reduction.
Photo Restoration Options
The first slider in the photo restoration options of this filter is noise reduction. This does not specifically target color noise as that is the next option.
Color Noise Reduction
On the other hand, color noise reduction specifically targets any color noise that may be introduced due to the increase in contrast, saturation, etc. either from the photo enhancement option or just the photo itself.
Halftone Artifacts Reduction
Halftone Artifact Reduction works to reduce the circular halftone artifacts caused by various methods of printing usually present in older color photos.
JPEG Artifact Reduction
While there already is a neural filter for this available within Photoshop, this version is included for the sake of the workflow.
