Fits The Challenge-Yes
Composition-Beautiful.
Background-Right on.
My Opinion-I'm not a math wiz, but you sure have the eye for finding PI. Really a well done shot. Your an exellent photographer and I like your work. This shot has good texture, and nice tones along with perfect focus and composition. This was well recieved, keep up the good work.
I'm sure I'll figure out the third one soon... Anyway, I like this photo. The lines on the mill stone let me know that you are communicating radii here, and the bench is a nice touch. I can see pi at work here. Nice tones and focus, too.
Very well done. Love the toning here and I hope you get high marks for this very original idea. Took a few minutes to find the 3rd one which really gets the viewer involved here. Great job!
Very entertaining, very gray, colorful, designing, Pi place to visit. Great tones, good lighting at this time of day, good dof, nice focus, good and clear and sharp.
Clever. I see the millstone (obvious) and the water trough thing (subtle), but where's the 3rd sign? I like this as a photo in its own right. It has a crispness to it. Sepia tone is good, too.
Extremely interesting image. I like it for many reasons including the fact that you were able to find its use for this challenge. Great monochromatic and stark feeling to this one. I like the toning choice, too.
