We had about 6 or 7 of these portrait sessions last year and I think everyone learnt a lot. What I would like to do here is to start talking about portrait photography with 2 sources of light. Specifically I want to focus on a classic portrait lighting scheme that people like karsh and Irving Penn used to use.
The aim is to light the background from one direction and light the subject from another such that the lit part of the subject falls against the dark part of the background and the dark part of the subject shows against the lit part of the background. Very very dramatic.
We will use two flashes an umbrella and a couple of foam boards to make this happen. Results can be stunning.... By the way, not claiming to be a master of this technique, so we will all learn together.
