DAY 8: Slow Shutter Glow Stick Light Drag

 Several people have asked me how this picture was taken and if I did it on purpose.  Here’s a brief explanation without too much photogeek detail.  The shutter is the mechanism that opens and closes to allow light to hit the sensor.  The faster the shutter, the less effect continuous light will have on the picture.  If a slow shutter speed is used, any moving constant light source smears, as if painted on the sensor. For this picture, I shot it at 1/8th of second.
