What is an pinhole camera?
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.
How does an old camera work?
AnswerThis camera worked by putting film in this little compartment, and you pressed a button and then FLASH! a picture.this is the answerThe first cameras were pinhole cameras. They worked by the light from the outside. When that light shone through the pin hole, it flips the image on to the film and you have your pictures.
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.

How does an infra-red camera work?
Infrared (IR) photos are taken with normal cameras using infrared film. The difference is the film used, not the camera. IR film is sensitive to the IR spectrum of light, not the visible spectrum.
Why did joesph niepce invent photography?
He couldn't draw. Seriously. When Niepce was alive, a popular artist's tool was the "camera obscura." If you know what a pinhole camera is, you're one step ahead of the game here. Instead of using film, the camera obscura had a sheet of really thin paper in it. An image appeared on the paper; to make it permanent you traced it with a pencil. Niepce didn't have a steady-enough hand to make good tracings, so he invented a way to make the camera do the work for him.
Why doesn't the Pinhole camera model always work in real life?
Pinhole cameras do work in real life. They just do not produce as good a quality of picture as most of our fancy high-tech cameras do. Partly, that is because you cannot regulate the light as well with 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.
How does a CCD camera work exactly?
A CCD camera uses a special chip which detects light photons hitting an array. This data is then converted to binary which can then be interpreted by the camera into an image.
Why do three-chip cameras generally produce better pictures than one-chip models?
The sensor in an electronic camera can't actually collect color data. If you want color data out of an electronic sensor, you've got to put filters over the sensor and use electronic means to convert the information collected to color. A one-chip camera can do this in one of two ways. The designer can put a wheel with three filters - red, green and blue - in front of the sensor, or he/she can put a piece of glass with thousands of minuscule filters on it in front of the sensor, then tell the computer that processes the information, "if you see some data from position x, which has a blue filter in front of it, put that data in the blue channel." The first way doesn't allow shooting moving subjects, the second cuts down on the resolution you can get from the sensor - though you can compensate for this by just putting a better sensor in the camera. A three-chip camera uses a series of prisms to send the same image to three different sensors, and it has color separation filters in front of each sensor. The advantage is higher resolution. The disadvantage is the lenses have to be made for this system - the lens off a film camera or 1-chip digital won't work. Panavision's digital movie cameras use a 1-chip setup because of the lens issue: Panavision (which only rents equipment; they don't sell it) has a LOT of lenses in their inventory, and they didn't want to have to build all new ones for digital cameras.
What is the difference between pinhole camera and camera?
Pinhole was a slang term for A. a primitive type of camera with a very small aperture, giving maximum depth- but requiring much light, and B. this still in use- the smallest , and thus the deepest in depth of field aperture of any given camera or lens. My most modern Nikon F-80 has a preselected F/32 pinhole setting ( coded in as M) on the modal dial) this is great for distance shots of skyscrapers and the like on bright days only! Photo sensors will shift to a brighter aperture if there is anadequate light- such is progress. l25 ( shutter speed) and F-32 can work wonders with buildings.
How do you work the samsung captivate galaxy front camera?
There isn't a front camera on the illusion. What appears to be a camera lens on the front of the phone is actually the proximity and light sensor.
How do the shutter and lens of the camera work together to form an image?
In 35mm or digital camera there is a type of shutter or lens that controls how the outcome of the image is. These two things are very important in how the images exposure, depth of field, clarity or lack of, etc. effect the photograph. Behind the lens and shutter in a camera is the film or in digital, sensor chip. The film or sensor chip reads the light that passes through the lens. The shutter controls how much light is being passed through and the lens is what allows you to get the image that you're looking at in the same perspective and location as you want. The shutter speed can make images look like they're frozen, a slow shutter speed can make something look like they have movement. The Lens is the medium that replicates what you're looking through in the eye hole that makes the same image on the film or sensor chip.

How well does a small digital camera work compared to a big digital camera?
A small digital camera vs a big digital camera will work almost exactly the same. The differences are the features included. A big digital camera will have a viewfinder mechanism, an adjustable and interchangable lens, and a bigger sensor, while the small digital cameras will not.

How does a ccd video camera work?
In the past, cameras took still photos and videos by focusing light on film. Now, in a CCD video camera, the lens of the camera focuses light onto a small CCD sensor. CCD stands for "charge-coupled device."
