The basic way a pinhole camera works is that light goes through a pinhole (a very small hole in the front of the light-proof container) and hits the photographic paper at the back of the container, which reacts when exposed to light and creates the picture.

So, to apply this to an oatmeal box, get your cylindrical oatmeal can and find the center using a ruler. Cut a square (using a razor/exacto knife/etc- it helps to mark it first with a marker) about 1/2" by 1/2" in the center. Then take some Elmer's glue and glue the seam on the inside of the plastic lid, and around the seams on the bottom of the oatmeal box (this seals all the places where light could leak in). Then, find an aluminum can and cut off the top and bottom, and then cut it lengthwise so it's a flat rectangle. After marking a 2x3" rectangle, cut it out, and round off the corners so you won't cut yourself.

Now, spraypaint the can & lid black (this should be done outside) to make it completely lightproof. Now, take your aluminum rectangle and poke the pinhole in it with a pin (a sewing needle should work fine). Try to only push the tip in, just enough to make a hole- the smaller the hole, the more in focus your photos will be. Then sand both sides of the aluminum around the hole to make it smooth.

Next, take electrical/Duct Tape and place it on the two long sides of the aluminum. Then put some crazy glue (or just very strong glue) on the area around the pinhole - but NOT covering it!! - and attach the aluminum to the inside of the can, so the pinhole is peeking out of the square hole. This is your pinhole! (We use aluminum for the pinhole because the walls of the oatmeal can are too thick)

You can also make a shutter for it, but covering it with anything thick enough that will keep out all the light when you are not exposing the photo paper will work. Now just put photo paper in your camera and start experimenting!

How do you build a pinhole camera?

You can make a small pinhole camera with an oatmeal box--this is the traditional pinhole camera body. You poke a very small hole in one end of it. You put a piece of photographic film at the other end, and create a shutter out of a piece of duct tape. You can make a really large pinhole camera by doing the same thing but using your car as the camera body.

Improve a pinhole camera?

to improve a pinhole camera you can change the size of the box so that the picture appears clear and you can also capture lots of surroundings around you in the pinhole camera

What are the characteristics of a pin hole camera?

A pinhole camera is also known as a dark chamber camera. A pinhole camera is basically a camera in the shape of a closed chamber or box. On one of the sides of the box is a small hole which creates the image of the outside space on the opposite side of the inside of the box.

Which is older a box camera or a pinhole camera?

pinholes were the first cameras ever, so i presume they are older

What is the main working principle of a pinhole camera?

A pinhole camera is a simple form of camera. At it's simplest, this form of camera works by having a light-proof box with a small hole on one side - similar to a human eye.

What do you use to take photographs?

Usually, a camera. Occasionally, people take pictures with a cardboard box that they've converted into a pinhole camera.

What is the superiority of pinhole camera?

The pinhole camera is simple and requires no complex lens-based optical systems to work effectively as an image maker. In its simplest form it is no more than a light-tight box with a pinhole on one end and a place for a sheet of light sensitive material on the other.

What does the shutter on a pinhole camera do?

Like any other camera, the 'shutter' opens and closes to allow light to enter into the camera to be exposed on the film plane. A pinhole camera is a very primitive camera that does not have a lens. To put it simply, a 'pinhole camera' is a light-proof box with a small hole punctured in one side. Light passes through this small hole and projects an inverted image on the opposite side of the box. The smaller the hole, the sharper the image, but the dimmer the projected image. A pinhole camera's shutter is usually manually operated because of the lengthy exposure times needed. It usually is made of a piece of light-proof material to cover and uncover the pinhole. Typical exposures range from 5 seconds to hours and sometimes days.

How does a Pinhole camera work?

A pinhole camera is the most simple form of photography and requires practically no knowledge of photography to build a pinhole camera and capture an image using it. The basic principle behind a pinhole camera is the light enters through the pinhole at the front of the container (eg. a shoebox) travels through the light proof box and hits the photographic paper at the back of the box. The paper reacts to the light and where the light falls it is exposed (dark) and where there is no light the paper remains light. As you will be able to see after the image has been developed; the image produced will be a negative of the actual image. The image will also be upside-down due to the way in which the light enters the box. Then all that remains is to develop the photographic paper as you would normally. You will not see anything until you start to develop the paper. The paper will still appear white. Remember: - Light only travels in straight lines, - The box will need to be light proof apart from the pinhole at the front, - The pinhole cannot be too small, it can quite easily be too large, - Only place the paper in the box and remove it from the box in a darkroom. - Anything can be turned into a pinhole camera! Even rooms... Suggestions: - An old shoebox works well, as does a film canister. - Use black and white paper, it is easier to develop and far simpler to start with. Maybe experiment with colour afterwards. - You will need to use trial and error to find the correct exposure time. eg, if the image appears too dark decrease the exposure time, if it appears too light increase the exposure time. Have fun, pinhole camera's are great to make and a good introduction into photography. Alex Apps **************** - the aperture should be about 1/100th of the distance to the image plane visit for a fascinating story about the world's largest pinhole camera Micron

Who was the first man to invent a camera?

It partly depends on what you mean by camera; the first camera obscura (a room sized pinhole camera) was invented by Ibn al-Haytham in the 10th century. The first photograph was taken in 1826 by Joseph Nicéphore Niépce using a box camera.

How do you construct a camera?

A simple camera can be made simply with a light-tight box and a film or sensor, anything to 'capture' the light coming through an opening (lens, pinhole, aperture, etc.) Although this setup is rather rudimentary, it is a camera.

The screen in a pinhole camera must be translucent rather than transparent or opaque Why?

A focusing screen in a pinhole camera? A pinhole camera is a box with a very small hole in one end of it and a piece of film in the other end. The screens in reflex cameras and in view cameras are translucent to give the image something to form on. The light will pass through a transparent screen without forming an image, and it won't go through an opaque screen at all.

When was the first camera finally completed?

The first photograph was in 1825, we would have to consider that a camera.But the camera itself, just a box with a pinhole, was described already 300-400 BC. The 2000 years between those two was the time it took to find a chemical method to make the image permanent.See also related link.

What is pinhole photography?

The most common type of pinhole photography is done with the aid of a shoe box. The film (use real black and white film as it is less sensitive to light and light leaks because we are talking about a shoe box here) is taped to one end of a shoe box and a small pinhole is carefully punched into the center of the opposite end of the shoe box. The box lid should be placed on tightly and sealed in place. When you handle the film, you must try to have total darkness. Practice all aspects of putting your shoe box "Camera" together in the light first. Place your finger over the pin hole before bringing into the light. Then the box is placed, usually outside on a sunny day. Point the pinhole end of the box toward something that you are interested in taking a picture of. Your subject has to be something that is stationary. The light coming through the pinhole will expose your film for you. Research the subject to help determine pinhole size and approximate exposure times to take some guesswork out your project.

What is a pin hole camera?

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. 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.

How does camera obscura work?

The camera obscure means "dark chamber" in Latin. Camera obscura can work with just a box with a hole in one side. Light from one part of an object will pass through the hole and to the paper inside. The image from the camera obscura will all be upside down and reveresed like a mirror. If the pinhole in it is smaller, the object will appear sharper.

When was the first film camera made?

The pinhole camera noted by Aristotle in the 4th century BC. later became known as the Camera Obscura, a term introduced by the Italians meaning "a dark room". The first pinhole did not use film, but the camera was so big eg, a room or box size, that the taker was acutally inside the camera and was simply tracing the images by hand. Kinda like paint by colors. And who knows, maybe the pinhole effect could have been observed from early man who saw images in caves produced by a small light opening in the cave??? Anyhoo, the Italians used the Camera Obscura during the 16th Century and was an aid by artist of the Renaissance eg, Guardi, Canaletto. Leanardo Da Vinci noted the possibility's of the camera. The "lens" did not actually come about until aprox. 1530 AD possibly by Daniel Barbaro.

How are pinhole cameras used in everyday life?

Can photography be done without a camera?

All photos are taken with a camera of some sort. The first cameras were called "Pinhole Cameras" because that is what they were: they were basically a lightproof box the size of a shoe-box that had a tiny sharp-edged hole punched through one side with a pin (which is where it gets its name from) and photographic paper inside on the opposite side of the box. It had no lens, knobs, dial, switches, or anything: about as simple as you could get. (Surf the internet for details: someone somewhere will have how to make one).

What is the first camera?

The name "Camera" derives from the words "Camera Obscura," which means "dark chamber." The principle of the pinhole was understood as far back as Aristotle's day, but the first good description of a pinhole camera obscura dates to sometime early in the 11th century when the Arab scholar Hassan Ibn Hassan, otherwise known as Alhazen, described the effect of a projected image through a pinhole into a darkened room as a means of safely observing solar eclipses. The "chamber" eventually evolved into a portable box for use as an artist's sketching aid. A lens was attached to replace the pinhole for the first time in 1550. The first successful use of the camera for photographic purposes was in 1816, when a Frenchmen named Nicephore Niepce made negative images on sensitized paper, though he was not able to fix them to prevent further action of light. He had succeeded in making permanent fixed imaged in the camera by 1826, but the resulting image was more like a lithographic plate than a modern photograph. So as you can see, the camera has evolved in both purpose and form over many centuries.
