Chromatic Aberration

Las descripciones de los efectos en esta página se refieren a los efectos predeterminados encontrados dentro de la pila de post-procesamiento.

In photography, chromatic aberration is an effect resulting from a camera’s lens failing to converge all colors to the same point. It appears as “fringes” of color along boundaries that separate dark and bright parts of the image.

The Chromatic Aberration effect is used to replicate this camera defect, it is also often used to artistic effect such as part of camera impact or intoxication effects. This implementation provides support for red/blue and green/purple fringing as well as user defined color fringing via an input texture.

Propiedades

Propiedad: Función:
Intensity Strength of chromatic aberrations.
Spectral Texture Texture used for custom fringing color (will use default when empty)

Optimisation

  • Reduce Intensity

Detalles

Performances depend on the Intensity value (the higher it is, the slower the render will be as it will need more samples to render smooth chromatic aberrations).

Chromatic Aberration uses a Spectral Texture input for custom fringing. Four example spectral textures are provided with the Post-processing stack:

  • Red/Blue (Default)

  • Blue/Red

  • Green/Purple

  • Purple/Green

You can create custom spectral textures in any image editing software. Spectral Texture resolution is not constrained but it is recommended that they are as small as possible (such as the 3x1 textures provided).

You can achieve a less smooth effect by manually setting the Filter Mode of the input texture to Point (no filter).
