|
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.
This is one of the photos.
The address of these photos
The laser pointers used are all from CNI laser |

We were doing that 15 years ago. Not new, but still very cool. _________________ And the sun sets on Pentium Prime, hopefully to rise again. |

This technology of taking photogragh is old. But the laser pointers we use are new. And this video using so many colors of laser pointers. |

That looks real cool. What was the process to make it? Are you shooting at some material that retains the light? Or is it all done in post video processing? |

That's real time video. The only video processing was to reduce the file size.
