Processing by Nokia! Fascinated by the water coloury cloud and its water coloury reflection in the water, curvature of the earth/lens and the sharpening at lower sides.
There is a lot of movement in this shot. They are brave souls to be on such a fragile looking structure :) I like how the sky (quite a dramatic one)draws my eye to them - nice job in your b&w conversion.
Those are some pretty wicked looking clouds, but I feel like they got a little over processed. It almost looks like paper that has had multiple water stains on it.
I like how the people seem so small and insignificant compared to the approaching storm. Something a bit funky with the processing, though. I see a lot of blotchiness in the clouds and in the center portion of the water. (I do have a monitor that is a bit on the bright side and does show artifacting when others may not see it.)
