Why Black and White? The corporate identity of each of these brands relies heavily on colour....to lose that is losing part of the strong identities you are playing off each other as opposites.
Clever subject for this challenge. I think there are some technical problems, though. Your depth of field seems too limited--the " pepsi" at the bottom of the can could be in focus. The lighting is a bit harsh--especially evident in the highlights at the top of the coke cans. The background is neutral but the subjects fade into it at the edges. The b&w is a nice choice and the things I object to do lend an "artsy" feel. Just think it could be done a bit better.
So which do you drink? Background is, perhaps, too light - which doesn't allow your objects to consume the entire grey scale. The words "Coca Cola" are white on a can, but appear neutral grey in your image. You definitely captured "opposite" though.
haha, take that pepsi, i love how it seems the two coca cola cans crushed the pepsi can, its very nice in black and white, and the softness is wonderful! 9/10
Overall, it's a nice shot. I like that you chose to do it in black&white. On the negative side, I do not think that this picture shows opposites. They're competing products, but it does not make them opposites of each other.
Well done, I like it. Good use of BW. Perhaps you could have used something other than a towel under the cans. You can see the weave of the cotton. Plain white paper could have worked better. 7
Guess Coke won, huh? Nice shot - very nice job of "printing" the black and white - with crisp whites and deep blacks evident. The top of the center can is a bit soft, but not enough to deduct any points for. Likewise the bottoms of the cans have a jagged edge (guess they are sitting on some kind of cloth?) Overall - a very competitive entry (pun intended.)
Nice thought and good for the subject, but I get the feeling the b/w hides a less than perfect shot? Would have wanted it in color I think. Also it's very centered and staged. I think you could have worked with the dof better and added depth, perhaps putting the cans in a diagonal? Shaprness on the front of the cans is very good, perhaps at the cost of too much contrast / exposure at the top. The shadows behind the cans work, although working in different directions, again adding to the "staged" feeling.
Next setup, try thinking a bit outside the frame. Not all of the subjects have to be all-in and in focus. Closest can could have been partial and out of focus, perhaps only the pepsi in focus towards the middle and then a faded out last can behind? Several pepsis out of focus with only one coke standing "focused and proud" in the middle or the other way around? Try different approaches and crops.
