Pencil Sharpener in Filtered Light

This is a pencil sharpener in my photography class at Pellissippi State. All the equipment I used to produced this interesting light was a small flash light and a pair of red and blue paper frame glasses that they give you to view a 3D movie. I put the camera on a tripod so I could take a long exposure. Camera settings: ISO 200 - f-11- 30 sec. exposure. With all of the lights off during the 30 second exposure I placed the blue part of the glasses in front of my flash light and began painting the sharpener then I do the same with the red side of the glasses.
