"You really just need light on the car. But when you are doing beauty stuff, I always put the sun behind the car because you need a clean pallet to work from. I always say that light is like a garden hose with a sprayer at the end and so you spray light onto the car, and do you want to focus it like a thin line, or do you want to spray it? What would you like to do and where are you going to spray it from? So, what part of the car are you going to get wet with light?" – Evan Klein
