I used to work as a production artist for a specialty ad firm. A lot of what your friend is asking is going to depend on the amount of detail there is in the original photo. I used Genuine Fractals to enlarge 72 dpi jpegs to a resolution I could use for a 65-85 lpi screen (most of what we did was silk-screen). But letters are notoriously difficult to do this to for two reasons. First you expect letters to have a particular shape and the enlarging process enlarges everything, including the faults that are in the image. It makes it hard to pull "good looking" letters back out. Second in most typefaces, especially one that would be used by an engraver, there are letters that look very much alike and a little loss in resolution can make their recovery difficult. Think C G O Q in caps, or P and R. Lowercase are generally better as you have the baseline to use, but c and o or i a

Personally I would suggest this: The SPD detective confiscated the original digital camera during the police search. Included in the camera kit was a set of apparently blank digital cards. Fortunately for the detective the criminal (s/he is guilty right?) simply erased the image, but did not reformat the card, meaning the original image is still there. The SPD detective takes the card and the camera to the optics/computer wizard who is able to pull the image from the card, read the exposure data, including the camera lens settings. He then is able to model the camera/lens combo and use that model to re-create the scene and, because he has the original image, is able to better enlarge the image thus revealing the necessary information on the knife. It has the benefit of at least bein
