dancepartydjs.com) provides photo booths for weddings and other events.

What’s the draw? In a word: Fun! Guests love to ham it up for the camera and a photo booth gives even non-dancers a reason to leave their seats. “Not everyone dances or drinks, but amazingly everyone knows how to act silly in an enclosed space for a camera,” says Josh Lynn of NJ Photobooths (973-580-0474; njphotobooths.com). (And in case you’re wondering, yes, there have been the odd guests who, um, overexposed themselves, but that’s extremely rare, according to the pros.)

Besides the in-the-moment enjoyment, the prints from the booth—which can be customized with the bride and groom’s names and wedding date or a monogram—make great keepsakes and wedding favors. Most booths create a double set of prints. Guests can keep one set and the other can be pasted into a scrapbook along with a note for the bride and groom—a clever update on the traditional sign-in book.

Considering snapping up a photo booth for your big day? There are two types available. The first is a hard-shelled wooden booth. “These offer the classic look and feel of a Boardwalk booth, which is a big plus,” says Lynn. “The downside is that they weigh about 750 pounds and require two or more people to install. Some venues may not allow them because they could scratch the floors or walls.” (Tip: If you rent a hard-shelled booth for an older venue, make sure the elevator is large enough to accommodate the booth if it needs to be transported to another floor.)

The second option is what’s known as a portable photo booth. These curtain, bench, and camera set-ups can be easily assembled on-site and the fabric curtains and backdrops can be changed to coordinate with your wedding colors. Prices for hard-shell booth rentals range from about $1,500 to $2,300, while portable booths cost from $1,000 to $1,500. Whichever you choose, set aside a 10-foot-square area to allow for the booth, a scrapbook-making table, and waiting guests.
