In most of my filmmaking experience I've always just used natural light or whatever lights happen to be nearby when on a certain location such as a lamp or whatever.
I want to screw around more with different types of lighting but I have a question. Let's say I buy a light that is strictly for filmmaking or photography and I use that in a scene. But, there is natural sun light shining in through the window.
Can I use two different types of a light in a scene? Would it affect it somehow?
