Smoke on the water
Long exposure in broad daylight of the volcanic rocks at Hamoa Beach near Hana, HI on Maui. And that's not fog, it's actually the waves coming in and out.
Turns out this is coincidentally my 1000th photo posted to Flickr. Woot!
30 seconds, f/11.0, and 100 ISO using a Haida ND 3.0 10-stop filter.
