I saw this youtube video
https://www.youtube.com/watch?v=KOVziSwbgss that appears to illustrate a method "used by the government?" in Photoshop to enhance a blurry photo whereby not enough pixels exist to make the image clear. I have CS6 v13.0.1 Expanded.
He appears to use some other version than mine. All I have that looks similar is the "Refine Edge" tool shown here
http://screencast.com/t/FRF3KVB18NA5 which is not the same according to what he says in his youtube video.
Assistance in following his steps on this are greatly appreciated.
"Then I found a leaked governmental Photoshop plugin which enables the user to do exactly the same thing as in the movies! I didn't find that plugin somewhere on the web, though, so I doubt there are ways to get it other than getting a leaked version from a friend..."
As you yourself have stated, there is not enough pixel information in order to produce the clear image that miraculously appears in the video. Pretty sure the "technique" used in the video is just the reveal of the original image that he had all along, because there's no way to get those results from the blurred image he started with.
