I'm a member of several meetup groups dedicated to photography, some of which put on workshops. The other night I attended a workshop on Light & Ink Master Lighting Class, hosted by PRO Photo Studio Workshops. Workshops such as these are a great way to learn and push your knowledge of studio light setups. You also gain valuable experience interacting with a model to work towards getting the best images possible.
The model for Light & Ink Master Lighting Class was Theresa Manchester. She was simply wonderful to work with, I cannot recommend her highly enough. Very professional, intuitive,
We worked through some different light setups with a mix of low-key and high-key thrown in.
A typical low-key setup using a soft box on the near right, with two strip on the left/right to add fill along the edges.
