I actually did this on purpose and I LOVE IT. I may even frame it for myself. Art installation is stacked glass, which creates a mirrored effect. The guard is walking around on the top floor, and I got him just before going out of my sight!
I was telling someone the other day that my style is Narrative Photography--and this is really what I mean by it! So it makes me feel good, even if it might not appeal to another person on the planet! Ha!
