Glow Features

The glow slider is for producing glow effects that emphasizes the outlines of the objects in an image. Although a low Glow slider value can be used to emphasize a sharpening effect, this feature is probably mostly used for special effects.

Glow Slider

Moving the knob of the Glow slider to the right will produce a glow effect, whereas movements in the opposite direction produce a shadow or antagonistic color effect. Clicking the color box at the left of the Glow slider opens up a color dialog for selecting a color for the glow effect. The default color is white, because that allows color-neutral glow effects.

Mask Sliders

The Mask Display options let you see the outlines of the glowing areas without the image itself or without parts of the image. It can also be used as a means of achieving special effects. While one of the Mask Display views is activated, you can use the Glow slider to colorize it.

If Mask Display is switched off, the Intensity slider intensifies the glow effect, the Smoothness slider widens it, the Remove slider shrinks it and the Expand slider brightens it a bit.
