It is technical day! Today we are going to try physiogram light painting! Don't be scared. The word is big but the technique is simple!
Simply put, a physiogram is a picture of a light pattern caused by a swinging light and captured by using long exposure.
Here is the step by step process
- Hang a torch or laser pointer from a piece of string from the ceiling.
- Set your camera exposure to manual, and use your smallest aperature and a low ISO setting. Set your shutter speed to 30 seconds (you can experiment with what works best for you). Put your camera on 10 second timer or use your remote.
- Place your camera on a tripod that can face upward (or put your camera on the floor facing up) and place it directly under your hanging light.
- Turn on your hanging torch. Turn off all the other lights. Swing the torch, and press your shutter button on your camera remote to start the exposure.
It's that easy! Experiment with different exposure times, coloured lights or multiple light strings! I used the flashing emergency light on a small flashlight.
There are many, many light painting techniques including spinning steel wool, waving glow sticks, and writing words with light from a flash light or sparkler. Try light painting today!
