HOW TO: Indoor Tornado
Earlier this week we had heavy rain storms come through the area. It was raining so hard and for so long, even I didn’t venture outside with the camera. No sense risking damage to expensive equipment when photography can be done inside under more favorable conditions.
It was so gloomy outside from the heavy cloud cover, darkening a room in the house for my photography experiment was pretty easy. After setting everything up, I closed the curtains and the door to the studio and got started.
Here’s how I produced this photo. I mounted the camera on the tripod and pre-focused on an area about five to seven feet away from the lens by taking a picture of myself. I then turned off the auto focus and set camera to manual focus. Then I set the shutter at 15 seconds, and the aperture was set at f8. I figured this was as good a place to start as any. I then set the self timer for a five second delay to give me time to get in position.
I turned off the lights, turned on the light source, tripped the shutter, moved in front of the camera, and started twirling my the light before the shutter opened. I continued to swing the lights around until I heard the shutter close, because the camera’s sensor will pick up any movement of the light.
What did I use for a light source you ask? It’s simple and inexpensive. Under six dollars, actually. I bought some battery operated LED finger rings resembling oversized jewels at a party supply store for two dollars each. I found a piece of string about six feet long and tied on some washers for added weight to one end of the string, and slid two rings down the string to rest on the washers.
Creating patterns is the fun part. Swing the light horizontally in a tight pattern in the beginning and gradually let the string slip through your fingers to allow the circles to get bigger to make a cone shape. Or swing the string vertically or any which way to create wild patterns of light. Experiment with different shutter times to see how the light changes.
I found through my many attempts at this, just how sensitive the camera is. Keeping the light pattern as consistent as possible is the hard part. It took many tries before I was able to keep from bumping the light into my legs or the desk or….some other obstacle. After a while, the light patterns stayed in a relatively circular pattern. But it took some practice.
Now that the weather has changed for the better, I’ll be heading back outside to do some more experiments using really long exposures and try to capture some ambient night light along with my artificial light. Woo-hoo!
