Last weekend I went on a Sea To Summit half day workshop to shoot the waves at Santa Cruz. It was good experience and I learned a lot. For one, I wouldn't have known how to find the great locations.
And for two, I would never have thought to be standing in
the moving water taking pictures. I also learned that I need more
filter power. Five stops ND wasn't enough to slow down the exposure
enough to capture the moving water effect in the day (curse Olympus's base ISO 200). But I did manage to capture two reasonable shots near to sunset:
Each exposure at one second. (The above shot is level btw. The "sloping to the right" look is an optical illusion probably caused by the cloud on the right.)
Unfortunately, not a lot of cloud, so no interesting sunset shots. Luck of the draw.
