Man there are some great pics on that site thanks for the links..
Yeah, Sam is a master at photography
Sam has lowered the resolution of the pics on his sight, but I can tell you that if you are willing to pay for them he will provide spectacular pictures. He does this for pleasure and for profit.
I had to laugh, an antenna farm I managed was hit by a mesocyclone and The first pics I saw of the damage were on the weather channel. Sam had already been to the sight and filmed it and sold the stock to the weather channel before I woke up L0L
Much of the footage you see on TV in news and movies was filmed by Sam, Carson and Tim Marshall
