Frequently Asked Questions

What is the ideal radius for sharpening web photos?

For general web viewing, an Unsharp Mask radius between 0.6 and 1.2 pixels with an amount around 80% yields optimal clarity without edge halos.

Does sharpening increase grain or noise in dark areas?

Increasing the Threshold slider protects flat and dark areas from noise amplification, sharpening only true high-contrast edges.
