The triangle is real. It's not photoshopped, in fact, this could have been submitted in a basic editing challenge as well even though I did do some minor cleanups on the edges using spot editing. It's an optical illusion of course. I found instructions for building this triangle here:
I seldom comment on frames but I believe this one really helps you image. I can never figure out how these impossible images are constructed. My only nit, the seam in the bottom left of the figure. If you can make the impossible figure, you could certainly eliminate this seam. ;) The tiny white line to the left of the thumb draws the eye but doesn't detract much. All in all, I love it and it will probably ribbon.
Well done. I can't see how you did it. The colour balance is a little cool, and the vignette is a little plastic looking, but the balance of the whole shot is good.
well, at this time this is my prefered photograph for the ribbon. great idea the optical illusion and well executed the photograph. I put this in my favourites and 10! good luck for the contest!!!!!!!!
