I was asked by my cousin's friend to take his headshots. Most of my work have been portraits so I'm I bit hesitant. I do however want to try it to see if it is something I'm able to do correctly. I mostly shoot outdoors in natural light. Southern California offers enough of that. My gear would be just my dslr, on-camera flash (not pop-up) and a reflector. Money is involved, another reason I'm hesitant. Since payment is involved, I want to make sure I deliver. Any advice on how to handle a headshot session? Or is it something I should pass up on?
