We were hired by marketing firm Moroch to photograph local McDonalds franchisees on-location at their office. For this type of scenario with multiple people to photograph, we try to make things as painless as possible. We set up a professional studio on-location with backdrop, wireless battery-powered strobes and modifiers, got the lights dialed-in with my assistant as a stand-in, and then between meetings when the owners had a moment to have their headshot made I only needed a minute or two per person.
