The lighting techniques wont really work on the latent prints, which I'm assuming is what the student is most interested in.
These need to be developed out.  

As finger prints contain salt, a rather poetic solution would be to mist the photograph's surface with a dilute solution of silver nitrate. Light sensitive silver chloride would form where fingers had been, this would then darken on exposure to actinic light and would present a permanent, easily photographable solution.

There is every chance that over time the photograph has become covered in a fine layer of salt from handling, so this approach could be quite dramatic and perhaps make for a nice video piece?

I believe you've got all the bits for this at Farnham but if you email me at work on Tuesday morning I'll gladly test it in the lab to see how well it works -  it will take only take 5 minutes and I'm curious myself.  >> [log in to unmask]" target="_self" tabindex="0" aria-label="Email address: [log in to unmask]" style="font-size: 10pt;">[log in to unmask]

Agree with Rene,
UV lights are the obvious option and will possibly give the best results.
Another trick if you are a Capture One user, is to do an LCC with a single light source hitting the surface only from one direction. This will enhance the micro-texture of the finger prints as it does with text or texture on paper.
This article is quite old but the procedure hasn’t changed:
Hope this helps

In my day, as a policeman, documents were soaked in a ninhydrin solution and then slowly dried out in a warm cupboard. Use to be 6 weeks before results come through. However, I suspect they have moved on since then.
Best way could be to contact the local Police station, SOCO department you will find them knowledgeable and helpful.
Kind regards

Hi Lisa
Not experienced in this but I think the police use UV fluorescence. If you have no luck please get back to me, I have a friend who is a scenes of crime officer, I can ask her.
All best

One of my BA Fine Art students would like to capture the fingerprints that appear all over an old photo she is trying to digitise from the 1950’s. Obviously this is something we normally try our best to remove, so if anyone has any tips/ ideas or experience of how we can highlight or show the fingerprints then I would be most grateful !
