As I understand it, the first use of light to help produce a picture was in
the mid 16th century, when a camera obscura was used to project an image
onto paper and the artist would trace around it.
The first recorded study of the light effect on silver salts was by Schulze
in 1727 who filled a glass bottle with a suspension of chalk and silver in
nitric acid. By attaching stencils on the side, he produced a print of the
image on the mixture. This was destroyed by over exposure to light, or
shaking the bottle ! Wedgewood tried to produce images to decorate the
plates he was making, cheaply. He had some success, but no means of fixing
the image and Humphry Davey, chemist, could not suggest any, otherwise the
history of photography from 1800 would be different.

Here's a link to the Niepce Museum http://www.niepce.com/
The oldest extant photographic image is in the Gernsheim Collection at the
U. Texas at Austin if I rememeber correctly. But other investigators like
Wedgewood had produced photographic images at around the same time but could
not fix them. Peter

Jean-Marc,
I think you mean the Christmas/New Year swap list if you just got a couple
images as have I. I checked and you are on that list too. The list of
participants in that Christmas/New Year swap can be found here:
http://www.rahji.com/noindex/pinholenewyear2004.php3?all=1

The PS4 is a more formal swap/exchange and info on that one isn't ready yet. The
swaps both of them are lots of fun and you get some great images from great
pinholers!
Hope this helps.
