This was shot with a Pentax manual focus 400 f/5.6 mounted to my 40D via adapter. The orange color is very dramatic in this view.
I hit Point Lobos in late morning light, and after a short hike down the Cypress Grove Trail saw some spectacular colors in the water.
I played with a 10 stop ND filter on a beach near the elusive Garrapata State Park that I was never able to be sure I found. The waves were coming in pretty good, but the longer exposure changes the mood of the scene.
