A few weeks ago I got to hang out with a very good friend of mine and during that time I had him show me this cool camera trick. He set my camera up so the shutter would stay open for a certain amount of time then we goofed off with some light sources. Apparently, when the shutter opens the camera absorbs the light which creates the picture. A typical picture can open the shutter for approximately 1/60th of a second. Some shutter speeds can be as fast as 1/500th of a second. Now that is pretty fast! We opened the shutter for 15 seconds and the images we created turned out pretty cool. Enjoy!
