The trick in food photography is to show the food looking fresh, so many dishes have stand-ins, just as movie stars do. "When I get my lights and cameras set up, I remove the stand-in and put in the real thing." explains Ray Webber, who photographs food for magazine advertisements. "Sometimes I have to brush the meat with its juices because it may have dried out a bit. And when I'm shooting（拍照）something like tomatoes, I always carry water to spray them with dew just before I shoot."

Shooting food outdoors has special problems. "I'm always worrying about flies or worms crawling up a glass," Webber explains, "my worry is that someday a dog will come up from behind and run off with the food." Once Webber was shooting a piece of cheese outdoors and needed something to make its color beautiful. Finally he found it: a weed with lovely blue flowers. When the shot appeared, several people were horrified—the weed was deadly night-shade!
