I shot this with a Canon R5 MK II on a tripod at 37mm, RF 24-105 F.4, 5 secs, F22 and ISO 100. I placed a crystal ball on top of a crystal pillar. I wound colored Fairy Lights around a black rod and in a totally dark room, stood behind the ball, triggered the shutter with a remote and waved the rod behind and across the crystal ball. Processed using Apple Photos to slightly lighten the colors.
