Sharpen Images Tutorial




Notes
The HSV Noise filter creates noise in the active layer or selection by using the Hue, Saturation, Value (luminosity) colour model.

Preview
This preview displays interactively changes before they are applied to the image.

Holdness
This slider (1 -8) controls how much the new pixel colour value is allowed to be applied compared to the existing colour. A low holdness will give an important hue variation. A high holdness will give a weak variation.

Hue
This slider changes the colour of the pixels in a random pattern. It selects an increasing available colour range in the HSV colour circle starting from the original pixel colour.

Saturation
This slider increases saturation of scattered pixels.

Value
This slider increases brightness of scattered pixels.
