Re: [pinhole-discussion] PS4
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. Ellis 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

subject: [pinhole-discussion] PS4 > Need info on swap and addresses of participants. Jean > 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. Chuck Flagg
