Sometimes you use something computer generated and need it to look photorealistic, and even if you have the best 3D renderer out there or even Filter Forge, sometimes they still have that "is there something weird about this?" look. This makes it look like you took a picture of it with a lame digital camera or had issues with your super awesome telephoto lens and that darndest thing called shutter speed.
