I agree that the clips on their site are very helpful.
Now imagine that clip streched out to an hour and include a bunch of info about how to use the wonderful Sekonic meters, and X brand strobes and Y brand softboxes, and by the way, if you purchase our other DVD on Subject Z it's full of great information.
As I said, maybe I just saw a lemon. It's possible the other titles are great, but I'm not willing to shell out the cash to find out.

The photots are really dated but the techniques are timeless.
I can't believe we actually wore clothes like that in the '70s!
