These computer generated images that youhave become used to are a fraud. Anyone who has worked in image processing will tell you that there is a margin of inaccuracy and that any image that is shown should be blurry and the more closely that they zoom in the blurrier it should get. All this nonsense that you see on CSI and other programmes about 'enhance' is pure fantasy. You can't create image data where none exists.
In this case the images were not computer generated.
