Shot this this morning, I have really ramped up the dehaze on this rendition to make it obvious but the sky is half purple half blue. It looks a bit like lens flare but I was in shadow, any ideas what the cause is?
It was misty lower down but reasonably clear higher up but you could be right, I shot quite few yesterday morning but this was the only one from that location in that direction and the sun is to camera left.
With the sun in front of the camera, any filter may cause flare which is why I do not normally use them. The effect initially may be slight but just trying the dehaze filter on a misty image, the saturation is increased significantly.
