Dave, I like the conversion very much. I like the leading lines and feel that the overall composition is pleasing. I might do another round of USM on the large rock.
Connie, Silver-Efex is a program that Niks software puts out. They offer a free trial and it is a fantastic program. I would recommend you try it for the free trial period. You will not be disappointed. Here is a link http://www.niksoftware.com/silverefexpro/usa/entry.php
Great image Dave. The lines are perfect. The B&W conversion and range of tones is very nice. The face of "ship rock" may be just a little dark but I am on a laptop...It's images like this that make you appreciate B&W so much.
Very well composed, Dave. I think you could really create some more pop with some selective burning and dodging throughout the image. I do wish the west side of the rock were a bit more in focus as everything leads your eye right to it. Still, it's a really strong image as presented.
