I'd like to have suggestions to prevent color fringing as much as possible; ideally, when taking pictures, i.e., before post-processing.
I understand that overexposed images may cause color fringing, or even harsh light, from what I can understand.
It happened to me, though, to see it even when shooting in the shade (but the sky is harsh bright). I'm not saying I see it everywhere, but it can definitely appear.
PS: I'm shooting RAW, with no DSLR pre-sharpening (Portrait mode is Faithful), Canon T4i and L-lenses (this question mostly relates to Canon 50mm f1.2L).
