Extermely tough subject and lighting condition to control. I admire your guts to try it. The dynamic range required to expose for the bright sky, reflections off the chrome, and the shadows must have presented a real challenge for you. A few to many blown highlights to be a winner I think. Having said all of that, the composition is eyecatching, and easy to look at. Nice effort.
cool escalator/stairway will be curious to see where this was shot -- over all the picture seems a little flat -- probably because you were shooting in a relatively dark area but with that bright patch of sky and red rock at the top and so the camera had some metering problems -- without some tweaks in photoshop I don't know what to suggest to help fix this
I like the composition in this shot but want more balance in the exposure. This would be a good candidate for exactly the kind of post exposure manipulation that's not permitted in this contest. If you could have shot several different exposures (from over to under exposed) then blended them in layers to have beautiful detail in everything from the shadows to the sky it would be great.
This is a great interpretation of the challenge... i like it! Of course, I would have enjoyed seeing a longer exposure to soften the water up a bit too :)
Subway entrance? It's a whole lot nicer than the ones where I live...nice symmetry, must not have been easy to get without people on the stairs. It might have been interesting at night.
