Thanks to http://fotografia101.com and Sylviarte I was able to construct this Dippold DYI pinhole camera. A pinhole camera is a simple camera that doesn’t have a lens and contains a small aperture in a light-proof box with a very small hole in one side. It has a similar behavior with the human eye in bright light. It projects the light from the scene through the hole in an inverted way to the film. It is manually operated. I use the template provided by Dippold in his flicker account.
After the construction of the camera I went to the Old San Juan area to shoot some pictures. These are some of the results.
