I shot this with a Canon R5 MK II on a tripod at 50mm, RF 24-105 F.4, 5 secs, F20 and ISO 100. I placed 3 different size crystal balls at the back edge of a horizontal mirror. I attached LED finger lights to a black rod and in a totally dark room, stood behind the balls, triggered the shutter with a remote and waved the LED rod up and down and across the crystal balls. I took dozens of shots and no 2 are the same. Processed using Apple Photos to slightly lighten and slightly saturate the colors.
