Optics
Vignette
Darkening toward the edges, the way a lens really falls off.
Controls
- amount
- How dark the corners go
- radius
- How far from the middle the darkening begins. Large enough and only the very corners are touched
- softness
- Width of the transition. Narrow makes a visible ring, wide makes an unnoticeable falloff
- roundness
- Whether the darkening follows a circle or the shape of the frame
- center x
- A number from 0 to 1, 0.5 by default.
- center y
- A number from 0 to 1, 0.5 by default.
- tint
- The corners need not go black: film vignettes often drift warm or cold, and on light prints they go paler, not darker
