Pinhole Photography Day

Pinhole Photography day was produced to celebrate the skill of pinhole photography. At a time of continuously growing photography, Pinhole photography day celebrate the standard pinhole camera. Regardless of whether you own or make your own make certain that share you photos.

A PINHOLE camera is a camera without a lens. I have one myself. There is a tiny hole which focuses light onto film. Exposure times are always long due to the tiny aperture, so the camera MUST be tripod mounted. Shutter times typically can be several seconds, even on a bright day. The aperture on my pinhole camera is f235.

In theory, you can make a pinhole camera with your D80. You use the body cap which is used to seal the opening on the body where the lens mounts. A tiny hole is drilled into the cap. The camera then has to be used in bulb mode and the shutter held open for the correct exposure time. As the other answer said though, I don't know if the D80 will even allow any functioning without a proper lens mounted.

You can search Google for "homemade pinhole camera" and find info on how to make your own camera out of a matchbox and use film.

Here is a link on how to make your own fisheye lens out of a tin can.

How do yo make a basic pinhole camera ?

Get your box and glue down black paper/plastic all around the inside. Make a pinhole in the front and keep the pin in there. That's most easily down with a thumbtack. Make sure the box is light tight. Then go into a dark room and bluetack some photo paper on the side opposite to the hole and cover it up again. Just take the pin out when you want to take the photo.

What are pinhole cameras? How do they work?

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.

Because a pinhole camera requires a lengthy exposure, its shutter may be manually operated, as with a flap made of light-proof material to cover and uncover the pinhole. Typical exposures range from 5 seconds to several hours.

A common use of the pinhole camera is to capture the movement of the sun over a long period of time. This type of photography is called Solargraphy.

The image may be projected onto a translucent screen for real-time viewing (popular for observing solar eclipses; see also camera obscura), or can expose photographic film or a charge coupled device (CCD). Pinhole cameras with CCDs are often used for surveillance[citation needed] because they are difficult to detect.

Pinhole devices provide safety for the eyes when viewing solar eclipses because the event is observed indirectly, the diminished intensity of the pinhole image being harmless compared with the full glare of the Sun itself.[citation needed]

World Pinhole Day is held on the last Sunday of April.

A pinhole camera is the simplest camera possible. It consists of a light-proof box, some sort of film and a pinhole. The pinhole is simply an extremely small hole like you would make with the tip of a pin in a piece of thick aluminum foil.

A pinhole camera works on a simple principle. Imagine you are inside a large, dark, room-sized box containing a pinhole. Imagine that outside the room is a friend with a flashlight, and he is shining the flashlight at different angles through the pinhole. When you look at the wall opposite the pinhole, what you will see is a small dot created by the flashlight's beam shining through the pinhole. The small dot will move as your friend moves his flashlight. The smaller the pinhole (within limits), the smaller and sharper the point of light that the flashlight creates.

Now imagine that you take your large, dark, pinhole-equipped room outside and you point it at a nice landscape scene. When you look at the wall opposite the pinhole, what you will see is an inverted and reversed image of the scene outside. Each point in the scene emits light, and, just like the flashlight, the beam of light from that point passes through the pinhole and creates a point of light on the back wall. All of the points in the scene do that at the same time, so an entire image, in focus, is created on the back wall of the room. The image is very dim because the pinhole is so small, but you can see it if the room is very dark.

A pinhole camera is simply a smaller version of that room, and the film inside the camera replaces you. The film records the image that comes in through the pinhole. The camera records a nice, in-focus image of the scene that you point the camera at. Usually, you have to expose the film for a long time because the pinhole lets so little light through.

The pinhole in a pinhole camera acts as the lens. The pinhole forces every point emitting light in the scene to form a small point on the film, so the image is crisp. The reason a normal camera uses a lens rather than a pinhole is because the lens creates a much larger hole through which light can make it onto the film, meaning the film can be exposed faster.
