Simulates flat chromatic aberration and a vignetted lens.
— X and Y Position: Let you change the center of the effect within the frame about which chromatic aberration is created.
— Blur Strength: Lets you blur the primary image.
— Aberration Distance: Adjusts how far the aberration effect appears from the source image.
— Aberration Strength: Intensifies the zoom blur used to create the chromatic aberration effect to intensify it.
— Vignette Size: Lets you add edge vignetting to the image; setting this to 0 removes the vignette, while 1 is the maximum size of a vignette using this filter.
— Vignette Sharpness: Lets you adjust the feathering of the vignette effect; lowering this value softens the edge, while raising this value sharpens, but never fully eliminates the softness from this edge. The Vignette effect is designed to fall off in a way that simulates how a lens would exhibit vignetting.
Scanlines
Simulates television scanlines, or any effect where you want alternating lines to darken the image.
A variety of parameters makes this an extremely flexible effect that can be applied in numerous ways.
Appearance
Let you customize the type of scanline effect you want.
— Line Frequency: Lets you choose how many or few lines are superimposed on the image; fewer lines automatically space themselves to be thicker as they’re uniformly distributed across the image.
— Line Sharpness: Lets you blur the border between each line, softening the effect.
— Line Angle: Lets you rotate the lines to appear at any angle; the default is 0 which results in horizontal lines.
— Line Width: Lets you increase or decrease the width of the blanking lines that obscure the image (which default to black but are tinted by the Color 2 parameter), thus increasing or decreasing the amount of image showing through.
— Line Shift: Lets you offset the lines being overlaid on the image. Animating Line Shift lets you create a rolling scanlines effect.
Color
Lets you tint and shift channels of the alternating scanlines created by this filter. Exaggerated, this can create numerous other stylistic effects.
— Color 1 and Color 2: Color picker and eyedropper controls that let you tint each alternating set of lines (eyedroppers let you sample a color from the RGB image being input into the current node).
