This is a great idea. These folks bought fast food items and photographed them, then placed the photos side-by-side with the photos in ads for the same product. Shown here: KFC Famous Bowl
Each item was purchased, taken home, and photographed immediately. Nothing was tampered with, run over by a car, or anything of the sort. It is an accurate representation in every case. Shiny, neon-orange, liquefied pump-cheese, and all.Link (Thanks, Stephen!)
I worked (briefly) in the photogoraphy studio of one of the biggest ad agencies in NYC. They paid a professional "food stylist" around $2000 a day to make the food look like that. Every golden sesame seed or drop of crystaline dew was hand placed. That maoynaise isn't mayo, it's hair gel and that chicken looks so good because aparently everything looks yummier when it's been sprayed with laquer. A lot of that "food" isn't food at all and the stuff that is food has been treated with more chemicals and "tricks of the trade" than most super models.
