Chromatic aberration removal in Photoshop CC
I have a question about CA. I was in the middle of editing a photo in PS and noted some severe CA. I didn't want to start all over so I found a method in PS for removing and I am curious as to why this would remove CA.
Change blending mode to color (I made the layer a smart object first)
Apply Gaussian blur (in my case 23.5).
And low and behold it removed all the CA. Why?
This method did desaturate the image a bit.
Creates a result color with the luminance of the base color and the hue and saturation of the blend color. This preserves the gray levels in the image and is useful for coloring monochrome images and for tinting color images.
