Re: digital pinhole

Hi-

There is another direction for digital pinhole cameras- steal some
tricks from the Astropohographers. They have a similar problem- they
need long exposures to gather up enough star light to make an exposure.
And many of them are using digital cameras. They get past the noise
problem by cooling the CCD chip, and stacking many exposures together.
It is a B&W camera. Want color? Just make a red exposure, a green
exposure and a blue exposure...

University Optics <http://www.universityoptics.com/ccd.htm> sells a book
and parts to build your own camera. An astrophography web search should
turn up a lot of other good sites.

The only problem, it is a pretty expensive solution,

Cheers
Mike
