beautiful!! at first glance I thought it was a stairwell, but then I saw otherwise. fantastic use of black and white, although it would be nice to see just a tad more detail towards the bottom of the shell.
beautiful. the b&w treatment adds to the simplicity and has me focus on the form and shadows - you've given the shell a luminessence (? spelling). the soft focus adds to the effect. One of my favorites this challenge
Very nice shot. My one suggestion would be to soften the light a tad. The lower right hand side looks a little blown out on the edge of the shell. That is just a little nit-picky. I still think this is an excellent shot.
