I have a question to mull over your morning coffee with! We make UV lights which are used for counterfeit detection. They work great on currency. Now I need to show how well they work on IDs like US drivers' licenses, passports, etc. I see the results, but my camera doesn't. My camera DOES see the strip in a US $100 note, but not my passport or license. Anyone tried this and can lend some info? I'm going to try a RAW file and play with the color sliders, but we really need to say the photo is un-retouched. Using a filter is okay, and I'm exploring that as well.
