Effects - Soft-focus

Soft-focus is probably the most famous type of filter effect in real-life. It's applications range as wide as landscape to portrait photography.
It has been used to create smoke, fog or haze effects, romantic touches to portraits or product photography or to smoothen skin texture in model photography.
A soft-focus effect scatters incoming light, resulting in slight blurring.

Settings

Strength

This control determines how much the soft-focus effect is applied in general. A higher strength scatters light more

Gradient

Sets the gradient mode used for this effect. See below for details.

Gradient bar

The gradient bar shows a horizontal representation of the gradient used for this effect. It works similar to gradient tools in graphics applications.
In the middle is the bar and at the bottom are "points". Working with the soft-focus gradient bar is similar to the one used in the Color effect (just the transparency part is used here).

Gradient modes

There are a number of modes which determine the "shape" of the gradient.
