Not sure why you would caption this 'triangles' and then submit it as a supposedly subjectless photo. Still, I'm not holding this challenge idea against anyone. The subject matter is interesting here and I like how you've presented it in black and white. I think a slightly stronger touch on the contrast would have benefited this by adding a little more pop and keeping the photo from washing out some. As is it borders a bit on being a mass of middle tones. I like to see black blacks, white whites, and everything in between. Overall this is a great entry, good luck.
Beautiful! I like the duotone treatment a lot. This is a perfect example of an image without a subject that is still an extremely appealing image. The lighting is gorgeous, too - I like the darkness of it.
I can't help but search for any 4 leaf clovers in a patch, and this shot is no exception. Love how you brought out the triangles within the round clover edges. Fantastic idea!
