“Defringe: All Edges” or “Defringe: Hightlight Edges“.“Defringe: All Edges” will remove the colour fringing, but also results in subtle
grayish lines. For my image this solution appeared to be the optimum. The defringed
image tends to be a little bit desaturated, so I recommend you to slightly increase
the saturation and if needed contrast. It might be helpful to have the original
layer and the adjusted layer in your layers palette to directly compare what values
of saturation/contrast fit the most for your project. “Defringe: Highlight Edges”
is to be used if most of the colour fringing occurs in edges of highlighting, which
is quite often the case. Just feel free to play around with the sliders."

can display fringing as it is dependent upon the lens PLUS sensor/AA filter/other
behind-lens optics
plus the interaction of the raw conversion process. It is very
complex ... A simplistic ".. older designs are better ..." analysis of the problem
isn't very informative or accurate.”
