Switek Entertainment, Chicago

In the curtained-off confines of a photo booth, revelers adjust a digital screen’s controls, then mug for the camera wrapped in feather boas, eyes obscured behind sunglasses. The props and the booth come courtesy of Switek Entertainment, whose photo booths and chief disc jockey—who spins under the name DJ Switek—energize crowds at Michigan wedding receptions and parties. The company also draws on connections to other area businesses, matching hosts with party essentials, such as guests who can put their hands in the air for the entire duration of an event.
