Thank you for all the comments. Now, for someone who wonder how I made this photo. I printed a piece of paper with diagonal o-line, rolled it up as a tube and attached a piece of curled paper onto one end. Then I photographed it through the tube with flashlight to cast shadow on the background wall. For post-production, I adjust bightness and contrast (it didn't seem enough) and inverted it.
I like it! I have no idea what it is but I like it...lol I'm trying to come up with a guess, but you have me stumped! Some sort of light reflections on a wall or ceiling? LOL Hope you'll tell me later. Grayce aka Gracious
Very cool effect shot. I need to remember to look up the comments on this to see how it was done! It's a cool visual, but the illusion...infinity??? 7 Swash
