This is Corona Del Mar, CA in Orange County and it's my new favorite beach in So Cal. It's only 30 minutes from my office too. Sean Foster pointed it out to me so, thanks Sean. These rocks really do look like petrified wood.
If you have time, I made a little video of the processing of an HDR
image (not this one) it's really fast but still long. It's the most
simple HDR I could find so check it out by clicking VIDEO
if people like it I'll make a speaking tutorial.
