It's pretty simple but I found it to be a good way to get a nice soft light for portraits. I had an ancient 80's BRAUN flash that takes 45-90 seconds to recharge. I didn't want to use it but wanted the soft light of an umbrella, and I hadn't tried it before..
I just put the umbrella on the stand and great light! [5d with 50mm Summilux-R Fotodiox adapter]
