Hey Guys,
Setting up the lights in different locations can definitely be tricky. I am always a bit self conscious when I am doing it as I don't want to spend 20 minutes in the home getting the light perfect.
" I always use umbrellas for bounce and I always set the lights up the same way: 45 degrees to the subject. And I calibrate exposure with a flash meter."
Jim - Essentially this is what I do...I find that I have gotten much better at getting the light even throughout the photograph.
