We were shooting in a bar/restaurant last Friday and one of the things we wanted to get out of the shoot was casual, candid images of people at the bar. There's a thousand ways to do that starting with the most expensive: Have a casting call, book professional models, bring assistants and light the place up. Direct. The opposite strategy is to find good looking or interesting looking people as they come through the door and offer to buy all their drinks and appetizers in exchange for signing model releases that allow us to use the images. Since single location restaurants aren't always in possession of enormous and extravagant advertising budgets we chose the second option.
