Being a photographer, I’m always on the look out for cool creative photographs.

Singlatheorist.com’s post on roomba’s cleaning path showed an excellent use of the long-exposure technique. In his case, he used a 30s exposure (and a Canon XSi, my all-time favourite camera.)

To achieve this technique, it’s actually pretty simple.
1) Turn the command dial on your camera to “Tv”. This is your shutter-priority mode. The camera calculates the size of the aperture.
2) Dial down the shutter speed to your desired duration.

Tips:
- These kind of shots work well to convey motion Adding a light source into the scene that moves during the exposure will leave a very interseting light trail.
- Dial down the ISO to eliminate noise and to gain control over the aperture.

Give it a try!
