You CAN Build Everything With Lego, Even A Pinhole Camera
The only exceptions are a little bit of black electrical tape and black painted foil for prevent light leak.
Giacomo uses Ilford PanF film, 50 iso which he exposes for about 1 - 5 seconds depending the lighting conditions. The reason for this specific Ilford PanF film is that it compensate very well for minor exposure errors. The size of the exposed film is about 24X80 mm. kinda usual, but gives wonderful panoramic results.
Giacomo says that the camera was inspired by Found Photography's Lego cameras archive. Having looked at it, this archive is an incredible resource if you are looking to make a Lego pinhole for yourself. More images and results after the jump.
