receiving a lomography newsletter promoting its new diy pinhole camera prompted me to post here about pinholes. even though i'm an "experimental" photographer (i use a lot of crappy old toy cameras, etc) i've never made a pinhole, and i have a good idea for one - maybe it will be a summer project!

ABOUT PINHOLES[/FONT]
[FONT=Georgia, Times New Roman, Times, serif] A pinhole camera has no lens. In its place is an extremely small aperture (f/138 for the Zero Image Pinhole's) through which exterior light is projected onto sensitive film or paper. A lens functions by collecting the light rays outside, inverting them, and focusing them into a smaller image. A pinhole does not focus at all. It merely acts as a "center of projection" inverting the light rays without re–organizing them. The size of the inverted image depends on the distance of the pinhole to the projection surface – a closer distance yields a smaller image and vice–versa. As the hole is not truly a point, it allows more than only one ray from the subject to register on the film. This imparts a characteristic "soft focus" effect. Moreover, as the light is not altered, the pinhole has nearly unlimited depth of field, with reasonably close objects registering at the same sharpness as far away objects (okay, REALLY close objects will be blurred!). As the pinhole is so tiny, it yields a wide–angle focal view and reproduces true geometrical lines, unlike the usual curved effect of a wide–angle lens. It also requires a fairly long exposure time – about 2 seconds in bright sunlight!

[/FONT] if anyone has made a pinhole, share your stories! i'm excited to try my idea, it involves very little building and will be small and portable enough for trial-and-error.
