I have an image which is watched through a lens.
Due to the quality of the lens I see chromatic aberration especially for black objects on white background.
In Blender there is one node called ‘Lens distortion’. If you set the Dispersion value to e.g. 0.2 you can simulate this chromatic aberation effect.
What I want to do now is to render my image with the negative dispersion value of -0.2.
The result will be an image with inverse chromatic aberation. If I watch this image through my lense again I hope to eliminate the chormatic aberation. I don’t know if this will work, but I want to give it a try.
Unfortunately the Dispersion value in the blender node can only take positive values :(.
Is there any way (may an additional node) to inverse the result of the dispersion somehow?
