What is this ring in center of the photo?

[nerwin]

So I was messing around with a photo I took of a gull today with my RX100 M3 in Lightroom and lowered the luminance of the blue to -100 and noticed this ring around the center of the photo. It only appears when lowering the luminance of the blue.

I know lowering the luminance of certain colors and make photos look really strange, but I never seen it make a ring around the center.

Anyone know why that is?

Force field or the bird about to hit mach 1?

Looks a bit like a Newtonian ring.

If so, wouldn't there be more rings?

Watermark. Bird is tired of people taking his picture without a signed release

Not if two lens elements only touch in the center of each glass and not all across the surfaces.

Hmm very interesting. So it's probably something to do with the lens design.

Many lenses employ that design. Simply Google "Camera Lens Elements" and click on "Images" and you'll see cross-sections of various lenses, and you'll see it.

Now I do, on my iPad in the enhanced version but not really in the op

I can't see it on my tablet either unless I crank the brightness all the way up.
