What an interesting image. Well done. I wonder...if you were not shooting for the challenge, your main point of focus could have been further in to the image. I love the contrast between a water tower and cactus.
First, on the technical aspects of this photo: the use of the railroad tracks as leading lines in to the desert landscape, right to the water tower, is perfect. The inclusion of the giant saguaro cactus really adds to the impact of this shot. And the mono conversion was done very well.
Now, on another note: I really love Arizona landscapes. I grew up down there, and seeing things like this really makes me miss the area. This is a very nice photo.
I like this shot. It's got a very "Ansel Adams" feel to it. Nice depth of tones - all the way from black to white.
The composition is great too. Perfect for the challenge. The tracks lead your eye right in.
Good DOF - sharp right from the front all the way to infinity.
Well done.
I did not get to this one during voting, but this is excellent composition & use of B&W. This has an excellent range of contrast. Should have been voted higher IMO:)
