Save for a few random photographers, all the technical stuff tends to land on the responsibility of assistants. I’m of course talking about my world. I still handle all my own digital (b/c my clients know that I don’t really need a digital tech) but I have an assistant for every shoot handling the light for me. I don’t have to think about it. He knows what I like. We are “sympatico”. If I had to do it myself, I could, but I would just prefer not to. It all really depends on budget whether you get an assistant or not. I would rather take a pay cut to have the help I need than to do it all on my own.
