Jimmy:
This is something I've thought a lot about.
When it's someone's money, I give them what they want. If it's not "technically" correct but it's what they want, it's what they get. They're happy and I'm money ahead.
When it's my time and money I keep the technical aspects in my hip pocket and go for the mood I'm in. I'm always experimenting with light modifiers to help create my mood and then write the technical aspects down so I can recreate it again if I like it.
I haven't stopped to count how many setups I can put up without thinking about them but I know there are more that I don't know how to set up that I want to try but the bottom line is the end result. Was it achieved through the models look, the technical aspects of the lighting or the mood I'm in when I shot it or later when I see the final product.
Pass the bong over here and see if I can not answer your question any worse than I already have.

Not technically correct, but it's what I wanted and I like it. If others don't like it, well, tough ****t.
