How do cameras work?

Answer 1

Cameras are of two types

Digital:

These cameras have photo sensitive transistors which actually help to generate different voltages for different colors of light and they get converted to different values through a ADC and are processed to generate a picture.

Older cameras:

They contain silver compound (mostly Agcl) coated reel (photo reel which we buy) which is exposed to atmosphere for a split second when the shutter opens and thus by different intensities a different pattern is formed producing a photo. That is the reason negative cleaning is done is dark rooms.
There are several type of camera but a still digital camera captures an image and stores it as a data file. A still film camera captures light images on a light sensitive film which can then be developed into photographs.

Answer 2

In conventional movie cameras a motor drives film past a shutter at 16 frames per second for silent filming or 24 frames per second for sound and the shutter opens and closes once for each frame. A pull-down mechanism moves the film by one frame while the shutter is closed, and the film is at rest when the shutter opens for the exposure. This creates a series of still pictures that will appear to be moving when played back at the same speed. Faster rates projected at normal speed produce slow-motion effects. For slow motion at 1/3 normal speed, the film might be exposed at 72 frames per second and played back at 24. Slower speeds projected normally produce faster-than-normal "Keystone Kops" motion. In most other respects, movie cameras work just like still cameras, with exposure determined by shutter speed and aperture, with aperture being the primary variable, since shutter speed is standardized. (But some cameras have variable shutter openings which can be used for either special effects or exposure control). There are other forms of motion picture mechanism. Some high-speed cameras use a rotating prism to keep an image focused on each frame as the film moves continuously through the camera. There is no intermittent motion of the film in this type of camera, and such cameras can record frame rates in the thousands of frames per second. Others, such as animation cameras, are essentially still cameras that take many single photographs one at a time.

a video camera is a device that allows you to record what ever you are pointing the camera at. You can upload it onto sites like YouTube (most of the time). when you finish recording the video footage then you can edit it with different software and you are done. Hope I helped

Answer 4

Security cameras enable you to monitor and record any activity. Security cameras are able to do this because they can record , accept and transmit voice and audio data. This allows you to monitor activities that are happening in areas that are covered by security cameras. For example, you can watch over your home with the aid of a number of security cameras. It enables you to people who are about to approach the front or back door and can also be used to catch intruders in the act of breaking in.

Answer 5

The first cameras were pinhole cameras. They worked by the light from the image on the outside enters through the pinhole and flips it on to the film on the inside and the film captures it.

Read the article to see how they basically work. Hope this helps.

Answer 7

the same as normal camerahs work but they just don't get wreeked by water

Answer 8

the way video cameras work!
