necessary adjustments, and then do it again.
This is one technique where you really can’t go
wrong. You might really like some of the simple
designs or you might want to try some more com-
plex ones. Here are some techniques you can try
to create different patterns and effects:
■ Change the color using a gel. This is the
easiest effect to apply — just hold a piece
of colored gel over the lens for all or part
of the exposure. The white trails will turn
whatever color the gel is, creating more - Without touching the lens or changing the
focus, switch the camera or lens to manual
focus mode. - Set the camera exposure mode to manual.
Start with these settings: 30 seconds, f/10,
and ISO 100. If your camera has a Bulb mode
and a shutter release that locks, then you can
go for much longer. I have made many physi-
ograms that range from 60 to 90 seconds. - Start the flashlight swinging in a circular
motion (or any motion) and press the
shutter release button.
ABOUT THIS PHOTO The light from the flashlight creates a pattern as it swings. The pattern is determined by the speed of the flashlight and
the arc it is swinging. Taken at 61 seconds, f/10, and ISO 100.
