DIY Juice Box Pinhole Camera

Randomly Spotted on the Galactic Interweb…
I found this witty little video which demonstrates how to make your very own pinhole camera from a juice box. If you aren’t exactly sure what a pinhole camera is, here is the basic idea:
A pinhole camera is a very simple camera with no lens and a single very small aperture. Simply explained, it is 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. Cameras using small apertures, and the human eye in bright light both act like a pinhole camera.
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 screen.
A pinhole camera’s shutter is usually manually operated because of the lengthy exposure times, and consists of a flap of some light-proof material to cover and uncover the pinhole. Typical exposures range from 5 seconds to hours and sometimes days.
Have you made or used a pinhole camera? I haven’t (yet!), but some other Craftsters have! Check out this awesome matchbox pinhole camera and photos created by Lufah.
