Unsharp Masking / Sharpening

Unsharp Masking

For advanced sharpening jobs, PhotoDemon provides a full-featured Unsharp Masking tool. Radius, strength (amount), and threshold can be independently set, allowing for a variety of sharpening techniques. Unique to PhotoDemon is threshold feathering; pixels close to the threshold will be automatically feathered, to prevent the appearance of unsightly “jumps” in sharpening in the final image.

Like all PhotoDemon tools, a dedicated command bar allows you to save and load custom presets, randomize parameters, and reset to default values. Last-used settings are automatically saved and restored, and all changes provide a real-time preview (no click or mouse button release required).
