How to dance to psychedelic trance

Playing with my mini Maglite and the filter discs.

Dark room. Camera set at f/22 and 100 ISO with bulb exposure using a remote trigger. The total exposure time was 101 seconds for the blue dancer on the left and 47 seconds for the man on the right. Two images were merged on Photoshop.

I was the model and torch operator in both instances and used the torch to illuminate my bulbous face for a couple of seconds at the end of each exposure.
