Soft Focus
This filter creates an effect that’s similar to duplicating an object, using the Screen
blend mode to composite it against itself, and then blurring one of the overlapping
objects. The advantage of this filter is that you can do this all within a single filter. The
Strength parameter controls how much of the blurred image is added back to the
original image, while other sliders let you control the overall, horizontal, and vertical
amount of blur.
Parameters in the Inspector
Amount: Sets the radius of the blur. Values range from 0 (no blur) to 32.
Strength: Sets the amount of opacity of the blurred composite. Values range from 0 to 1.
Horizontal: Sets the percentage of the maximum horizontal blur.
Vertical: Sets the percentage of the maximum vertical blur.
Crop: Sets whether or not the object is cropped at its original boundaries.
Mix: Sets what percentage of the original image is blended with the blurred image.
Values range from 0 to 100%.
HUD Controls
The HUD contains the Amount and Strength controls.
Variable Blur
A blur which can either include or exclude a circular region, to create a sort of tunnel
focus effect. If the inner radius of the circle is larger than the outer radius of the circle,
the blur is applied outside of the circle. Otherwise, the blur is applied to the area within
the circle.
