I find this prop so unique in that it flips the image of whatever is inside of upside down. This is because of the shape and how it bends the light that goes through it.
In programs like Photoshop you can flip the image right side up through post processing, however, with good placement, you can also do the same thing without extensive editing. I had a lot of fun photographing this image on a bridge out in the middle of the woods :)
