Hole With lens
|
21st: Admin admin admin bloody admin. What a pain. Anyway. Pretoria Zoo asked me to bring back the shack. They were having a science week and wanted my camera obscura to be there as part of their displays. Previously I had used 9mm holes drilled into the walls as my apertures. This time I cut out a much bigger hole. I then installed a regular, un-ground lens, which I purchased from my optometrist. This was mounted in front of the hole. Results were amazing. The resultant picture was just about crisp enough to be able to read the writing on the sign outside.
