My dad got to go out there in the 90s on an unusual artist permit and painted landscapes for a few days. It sounded incredible. There was white shark research going on and he saw a seal get eaten through a spotting scope.
His website is tonykingart.com. It is sorely in need of an update. I don't have any photos of the Farallon paintings, but a small one hangs in my childhood bedroom. You could contact him through his site and I'm sure he'd oblige!
