This video is part 5 of a series by Thorsten Ott and gives a behind the scenes look at different shoots he has compleated. The main things I learned from the screening are that he puts a black and white film layer over the photo, in Photoshop with a low opacity, to change its look, and he mostly uses nylon screens and bare bulbs to give gradation to the light in his images. There are also some good tips on handling models and getting the results you are after from them.
