I’ve used a fair amount of Photoshop, and I have a rather good idea of the limits of improving picture quality. Basically, you can make it brighter, you can make it a bit sharper, and that’s it. So it drives me nuts every time a TV character utters those magic words, “can you enhance the image?” A 10-second flurry of pretend typing later, that blurry daguerreotype taken during a snowstorm that the detectives found in a whale’s stomach becomes clear enough that you can read a license plate number reflected in someone’s watch. Thanks, magical computers. Not only does it take me right out of the story, it also gives my co-workers completely unrealistic ideas of what I’m able to do with a real-life blurry photo.
