For me it was just right so, because I'm only gone into the flash photography and always find it interesting to watch pros on set. The DVD is well produced and Alexander is very well suited as a coach (I had the previous DVD "Creative Shooting" by him - this is actually more "scraping the barrel" and is also significantly more elaborate sets, including a "flour Shooting "). By the way are all video files as mp4 on DVD before, so you can copy it on a USB stick and watch comfortably on a Smart TV (my 5 years old Samsung TV for example, understands the format without any problems).
For beginners, I recommend flash in addition to the DVD reviewed here "creative flash photography" even the Book
"The lightning Cookbook: Creative flash photography in practice" by Andreas Jorn. With this combination, we are extremely well prepared for the start! :-)
