How was the first camera made?

The very first "Pin-Hole camera", by Ibn-ul-Hashiyam, which was no more than a light-tight box containing a photo sensitive plate at one end and a very small hole at the other. The small hole allowed for sustantial "depth of field" which precluded the need for a focusing lens. the idea was that the camera was rested on a secure surface or tripod, the hole was uncovered, and the light was allowed to enter the small hole for usually a number of minutes, depending on the sensitivity of the photo plate.... You can try this if you have access to a darkroom. Just use a piece of photo paper (protect it from any light before its exposed and until processong)...a shoe box works great. check the web for better detailed instructions..they're all over the place.
