I’ve seen on many crime shows that people will take pictures of license plates or security footage and will increase the image quality. Is this a real thing and if it is how does it work?

No. Totally fake. There’s no way to extract extra data from pixels. A picture is a picture. Sometimes changing the contrast and such will let you see details you’d miss, but you never increase resolution with after effects.

Not really. You cant enhance an Image like in the movies. That said, you can sometimes edit them to make things easier to see, but only if that Information is there to begin with.

For the most part no what you’re describing isn’t a thing because you can’t get more detail out of an image than what was in the original image even if you upscale it among other things the detail can’t go any higher than what it was originally captured at. Now more recently machine learning has become a big deal and using machine learning on images is a thing now. So you can basically use A.I / algorithms to add extra detail to enhance an image. Even then though the end result is just clever guessing /deductions by the A.I not what would have been in the original image.
