Maxxamillian, thanks for the constructive feedback. Had you taken the bet you would have lost, I'm afraid. No post production whatsoever was used in the creation of my picture.The photograph was taken inside the Church of the Jacobins in Toulouse, France, where Saint Thomas Aquinas is buried. One of the pillars is surrounded by a circular mirror, about waist height, which enables visitors to admire the ornate ceiling of the church without straining their necks. I happened to notice that the mirror, when viewed from a certain angle, produced the interesting reflective illusion you can see in the picture. Unfortunately the mirror is not one piece but in three sections and it is the break in one of these sections that creates the line you can see and spoils the trick somewhat. Still, I'm delighted to have baffled someone with it.

I was a bit miffed when I got home and found that in concentrating so hard on lining up the reflection that I blew out the stained glass window but it still makes for an interesting image.
