Is there a software package for Mac, Linux, or Windows that shows how to set up lighting or even shoots for video productions? Recently I have seen Mac software for photographers but that is very specific to photography equipment only.
It would be quite a lot of work, but possibly worth it for other benefits, but you could model your set/environment in Blender and then try out your lighting and camera positions using it.
The additional benefits are that you can greenscreen and/or generate special effects with the same model. It has been used for movies such as Project London.
Blender is a Free, Open Source, Cross Platform and very powerful 3D Modelling, Animation & Rendering tool. It allows you to position cameras and lights (of several different types) and animate their motions as well as the motion of scene elements.
