Long Exposure with a Laser Pen

This is just a long exposure shooting. There is nothing difficult. However, I would like to do some creative images with this method.

Changed it to black and white.

So far, I only have a red laser pen. I have seen there are some laser pens in different colours. That is good because only red is so boring.

It was not good to shine on objects in black as the black surface completely adsorbed the lights. Nevertheless, if I took a longer exposure and I had longer time to illuminate the whole scene, the object would become more obvious.
