Purchased this on a whim. If you are new to off camera flash or flash in general you may watch it two or three times. Mr Kelby does have a nice laid back approach to tuition which is great for beginners.
However if you a confident in: balancing available light with off camera flash, know what a pocket wizard is, understand how to darken a sky with a flash gun, know the difference between a beauty dish and a soft-box I would suggest this is not for you.
I got nothing out of it, but I have given it a 4 as to be fair it is a 4 when viewed by the audience it was intended for.
