A pinhole camera is a simple camera without a lens and with a single small aperture – effectively a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box. The human eye in bright light acts similarly, as do cameras using small apertures.
Up to a certain point, the smaller the hole, the sharper the image, but the dimmer the projected image. Optimally, the size of the aperture should be 1/100 or less of the distance between it and the projected image.
Here are some images of peoples work, who have made pinhole cameras out of a wide variety of different objects:
Pinhole out of an egg
Pinhole out of a pringles tube
Pinhole image out of some ones mouth
Pinhole out of a spam tin
Pinhole out of a camper van
Pinhole out of a peanut
Pinhole out of a potato
Pinhole refection of Woody
Pinhole made out of lego
Today we made our own Pinhole cameras and then went out and done an exposer of our own, and then developed them in the dark room. After doing this we scanned them onto the computer inverted them so that they were opposite to the negatives. Firstly we done this for 30 seconds and we found out that it was too dark, so we then knew we had to expose the paper for longer, so after that we went out and done another test shot and exposed it for 1 minute and this image and after developing it, it turned out better so then we then done an exposure for each of us filling the tin we made into the pinhole camera.
Below are the test pictures and my final negative and developed image.
This is the test one that we exposed for 30 seconds
This is the second one we did and exposed it for 1 minute
This is the negative to my final exposure
This is my final inverted image.
