I was doing some batch post-processing and I noticed something, really...really strange.
As you can see in the image below, there is a circular ring like thing, most probably chromatic error ? I mean, some part of mountain is clearly emphasized and is greener. While this can be some mistake on the side of automatic processing, or is it a defect in lens ?

I don't know. Since the lightening was already too low, and flare should not be that circular without a point source.

If you mean the VIBGYOR pattern, it does look a bit like flare or a light leak. If it is flare you should see it only in some angles or eliminate it with a hood. If it is a light leak you should start seeing in many other photos as well (though not necessarily all photos).

I just noticed that all the colours are there. It could be a glory. was the sun behind you?
nah its the lense flare from somewhere, there are a bunch of concentric circles

Maybe it's a lens flare. Sad that it ruined most of my photographs from that day :/
@ raja manuel, I don't think it's a light leak, since it would have been rather chaotic and random, instead of making a full circle.
