Im very sad to see such a bad fake halo pic here on SW...
Shame on the artist who fakes a fine natural phenomenon like this for the fame he might get. :-((( Also feel very sorry for the ones who give thumbs up because of being misinformed by photo forgers.

LandyGyebnar Looks a little too processed (which I never like) but what tipped you off,and no when I first saw it I gave it a thumbs down before I even read your post!!

Im the photographer, and I can assure that this was not faked.

This a stack of 7 individual images of varying exposures to capture the full dynamic range of the scene. It was felt it was necessary to do this to show in full detail the extent of the phenomenon. I took a properly exposed shot, 3 shots underexposed to capture the detail close to the sun, and I took 3 shots overexposed to capture the faint detail of the outer halo.

I believe that LandyGyebnar is most likely referring to the outer halo as being fake, but I can provide copies of the original shots used to make the image, and it is visible in all of the frames. The technique I used to make the image seen is called HDR, and it is used to expand the dynamic range of the normal photo by stacking and blending the 7 seven images into one, preserving the detail normally lost to a normal exposure.

I will admit that I overprocessed the image a bit, but I added no elements that were not in the scene naturally.

I can provide copies of the original frames if needed.

If its not fake, then physics dont work in Ohio...
1, The halo always have the red colour at its inner (sunward) side. The one on this pic has red outside...Ú
2, The size of the halo cant be fitted into a photo taken with 105mm focus
3, The size of the halo relative to the size of the corona should be MUCH bigger
4, If you check the pic again, you can see the tree branches behind halo circle... It can only happen when a strong diamond dust display is present but that needs extra cold and according to the temperature records on this day of Cincinnati the temp was above freezing all day, so diamond dust can be excluded.

So my conclusion: the circle is a lens flare exagerrated by the photographer and shown as a halo.
