Identifying Fake Images

[Man1c M0g]

With Photoshop and a little skill you can make the impossible come into life in front of your very eyes. But what about the times when you actually need to identify which images are real and which are fake? Well, OE Magazine have attempted to help us with an article dedicated to identying PhotoFakery. Here's a clippet:

Like it or not, fake images are everywhere and have become a part of today's culture. Thanks to the popularity of digital cameras and the availability of desktop imaging software that allows users to easily manipulate images, fake images have become commonplace, especially on the Internet. We see many images that defy common sense and it is natural for us to question the authenticity of these images. Most of have seen images that are obvious fakes, such as the 80-foot grasshopper climbing the Empire State Building, but we naturally assume that these images are fake and know that they were created simply for our amusement. Unfortunately there are too many times when a fake image has been created but it is advertised as real, challenging us to decide for ourselves whether the image is real of fake. A fake image can be defined as an image of an object or scene that wasn't captured as the image would imply. In general, fake images are created to generate a deception, but not all fake images are bad. The motivation may be simply for harmless entertainment, which accounts for most fake images generated today. Fake images can be generated for research and development purposes, e.g. to understand image quality issues with different camera designs. The fake images that concern us most are those that are created to perpetuate a lie. Some people will generate fake images for profit, such as a picture of an alien, a ghost, or an alien ghost of Elvis that they can then sell to a tabloid. Probably the most dangerous motive for generating fake images is to alter the public's perception of truth for political reasons. It would be nice a reliable method existed for determining if an image is real or fake, but unfortunately none exists. We can hope to catch most of the fake images, however, if we understand how fake image are made and what characteristics to look for.
