Hi everyone, while editing this photo we noticed a semi circle between the two mountains. Could you please help us figuring out if this could be the case of a lens flare or maybe something paranormal? The photo was taken in an ancient monastic site called Glendalough in Ireland.

Many thanks!

Lens flare?

I never experienced such a well defined/designed, single colour
and, most surprisingly, "behind the subject" flare.

Paranormal?

I am having too much fun dealing with the "normalities" of this
world so I am not competent with these matters.

Conclusion

This post must be a hoax.

Light is free… capturing it is not!

Definitely not lens flare. My first suspicion was an internal reflection but upon examination, it doesn't effect anything except sky. My conclusion is it is not from the camera but something done post capture to the image. A hoax, a test of peoples knowledge or someone doing something in post processing with realizing it would be hard to say. I have no explanation for it.

Thanks so much for your replies.

I wish this was a hoax. This is the original photo and the only thing I did was to reduce the highlights, and once done this perfect semi circle came out. We were so amazed that we have been trying to find an explanation to it.

That's what happened, when you made the adjustments in post for those highlights, there is very limited information there, so if you pulled back on saturation or highlights, the software created this.

You don't clarify, but if you shot JPG, and you're trying to edit a JPG, and there's glare right there, then you have no data. So your attempt to lower the highlights results in what you got.

If this was a RAW photo, then you have blown highlights, and again, no data of consequence. Scenes like this (strong backlighting) are best served by shooting to protect the highlights (don't STTR), or shoot multiple exposures and blend in post.

The highlights so appear to be that way, but I will admit I have never seen that happen before. If there is no data, shouldn’t those areas be completely white/grey? 

It would have to be happening in post processing. You might be able to superimpose a sky from another photo. I’m not very good at it, so im
not sure how to handle the highlights in the trees bordering the sky.

You got that right!

Or maybe it is a badly positioned watermark that is on a
lower layer with faint opacity.

Exactly! The RGB values within the semi-circle are 255,254,255 (not pure blown out white) and why do they appear in a perfect semi-circle? Perhaps something to do with how a digital sensor works?

And there are definitely no watermarks in this image.

Thanks again for your help.

Sensors read out line by line not in a circular pattern.
