Light Trails

[hawk1226]

Hey everyone,

I'm taking course in school and for my final project I was planning on documenting how light passes through different objects. For example, i left the exposure open for a long time and then ran a laser pointer across a blender. The result was pretty interesting because you could see the laser pointer being manipulated as it passed through the glass. My question therefore is what the best way to achieve this affect would be? I haven't been able to get the same visual change when doing the same process with different objects so i'm hoping there might be a better way to capture how light looks through different glass and clear objects. Any ideas? Thanks.
