i put the black light just inside the box and took the pic. (1) i also tryed to shining the black light right over the glow in the dark item, holding it there for about 30 sec. and taking the light away and then taking the pic. (2) you need to have your camera set up befor hand with everything set. i took the pic in a dark room, i did it fast just to show so i did not get the best pics.
