Drawing with lasers is really fun especially if you set your digital camera in stealth, long exposure mode.
How to use a laser pointer to draw, to write and to record it? I think it is a very interesting thing. With the help of a camera with the function which could set longer exposure time,you could easily record what you draw and write with the laser pointers.The laser pointers include 405 nm blu-ray laser pointer, 532 nm green laser pointer, 473 nm blue laser pointer, 593.5 nm orange laser pointer.
