Isn’t it nice when the foreground element nicely shows you where to look? And no I did not put the stones there. I have no idea why they were there, but I of course used them for the composition.
Looking back, I actually should have done another shot, with the camera a little more to the ground. But few minutes after I took this, a passing ship created a much bigger wave that I anticipated, and I ended with my shoes full of water, and I had to deal with that :)
This is a HDR from 3 exposures, created in Oloneo Photoengine, finished in Photoshop. I used a 10 stop ND filter while taking this photo.
