Chromatic blur
Blur that grows toward the edges, its own radius at every pixel.
Controls
- amount
- How soft the far corner gets. The middle of the frame stays sharp at any setting — lenses fail at the edge, not on axis
- falloff
- A number from 1 to 4, 2 by default.
- spread
- How far the channels part, which is what makes the softness coloured. At zero all three blur alike and no fringe is left
- contrast
- A number from -1 to 1, 0 by default.
