They say that "seeing is believing", but when it comes to TV commercials, this is not always the case.
The world's leading mobile phone maker, Nokia, released its latest model Lumia 920 on Sept. 5. The smart phone was supposed to possess an advanced camera, which let customers shoot better pictures at night and record stabilized videos. To show how well these features work, the Finnish company released an ad showing a man and a woman riding bicycles side by side, with the man taking a video of the woman on the phone. However, several hours later, technology website The Verge uncovered that the video was neither shot with the new product, nor shot from someone riding a bicycle. Instead, someone in a lorry next to the woman took the video using a professional video camera.
The next day Nokia apologized, "In an effort to demonstrate the benefits of visual image stabilization, we produced a video that simulates（看起来像）what we will be able to deliver." Indeed, what we have seen in ads is more or less a simulation——a practice called "advertising photography".
McDonald's video in June explained the "art". It showed how its burgers get dolled up（装扮）before going on camera. Like models preparing for a magazine cover shoot, burgers also get designed in a photography studio. They are prepared for hours and put together with absolute precision so they look their best before photo shoots. Each ingredient, such as onions and sauce, is carefully put into place to make the burger look much juicier, bigger and tastier. Computer software Photoshop is also used to add visual effects.
So don't feel ____________________when you get a burger that never looks like what you see in ads.
