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.A.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 nightshade!
