I have one idea in mind and I am not sure how or is it even possible.
Most of people have seen pictures where people have used UV paint and then they get some quit interesting pictures.
Like this one what I found by google:
What I like to to is use this type of paint and get similar results underwater.
I think that I am lost between flourescent and UV pictures.
Or if I use flourescent lights and filters should I get similar result like using blacklight on land?
