Their work goes on display together this Saturday, when a-d furniture interiors presents the exhibition "Duet: Photographs by Albert Watson and Sarah Moon." Misleading name aside, a-d has consistently devoted itself to filling its 3000-square-foot space with the work of major photographers, often being the first to unveil their images in Miami. This show, which runs through December, will close a triumphant year that featured shots by bigwigs such as Helmut Newton, Horst P. Horst, and Peter Beard. Also being unveiled on Saturday: upscale furniture and accessory lines by international design-world stars such as Sam Robin, Ton Luyk, Monica de Rhode, Alison Spear, and S. Russell Groves. Not one to be outdone, a-d owner Juan Carlos Arcila-Duque is more than just the photo curator. He designs as well. He'll show off his own work, too -- clean-lined chairs and tables that he created for the soon-to-be-open South Beach nightspot MYNT Ultra Lounge. "It's a very challenging view," Arcila-Duque notes of the show, "about what's happening design-wise in Miami."
