I have a project to do with my daughter then :D
I remember I created a small camera-obscura based photo-camera with friends for a physics project from piece o aluminium, old shoe-box and photo-paper :)
Reloading it was a pain, cause you had to be in a dark-room to put in in the box :D
Exposition was minutes.
It was awesome!
- taejo 7y agoThere are several photographic processes that are UV-sensitive, most notably cyanotypy, so you can work inside with the curtains closed with hardly any fogging, and then make photograms or contact prints outside. I've never tried taking photographs with it, but it could be fun too: exposure times in a pinhole camera are probably on the order of an hour, though.
- a-saleh 7y agoTo be honest, I don't really remember how long the exposistion times were. I assume we used less than hour, more than minute and I wonder if I can found our old lab-notes :) Photograms-idea sound really fun as well, and probably a bit easier than trying to get the exposition time correctly.
- taejo 7y agoTo be clear, my estimate for exposure time was for handmade cyanotype paper, not "real" photo paper.
