One of my favorite clients, Andrea, came to our studio on Halloween day dressed like the Cat in the Hat. She barely fit in the front door since her bonnet was so big. She was dropping off an executive for a headshot.
Of course, I could not let this just pass, so while my "official" subject was getting dressed in the other room, I snapped a few quickies. I just kept all the light stands in the same locations, but turned them toward the closest wall. This way I would not mess up any of the settings I made for the other portrait.
