Good food photography makes the food look fresh, so many dishes have stand-ins, just as movie stars do. “When I get my lights and camera 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 food with its juices because it may have dried out a bit. And when I’m shooting something like tomatoes, I always carry an atomizer(喷雾器) of water to spray(喷洒) them with dew(水珠) just before I shoot.”
Shooting food outdoors has special problems. “ I’m always worrying about flies or worms(虫) coming up a glass,” Webber explains. “I am also worried 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 add to its colour. Finally he found a plant with lovely blue flowers. When the photo appeared, several people were horrified(惊骇的), because the plant was Deadly Nightshade which can be very dangerous.
