Inkscape

This empty SVG file contains 2 filters for simulating a basic chromatic aberration effect. To use those filters, download the empty file 'chromatic_aberration_filters.svg' and put it in your Inkscape filters folder (for example, on Windows: 'C:\Program Files\Inkscape\share\filters\'). Then, the new filters will be available from the menu: Filters > Optical Defect.

The additive chromatic aberration filter decomposes the source graphic into its 3 RGB layers slightly horizontally offset. The alpha channel value of the source is preserved in each layer. Then, the layers are mixed using additive blending (screen blend mode). This filter is best suitable when applied to a light object on a dark background.
