Camera History



1.) Inside a completely dark room, a tiny hole is created in one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.
2.) In the 17th century, the modern camera came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.
3.) He added *film* to create the first successful photograph, and the modern camera was born.
4.) Light passes through the lens, into the camera, and exposes the film. And guess what? The end result is still a photograph
5.) Digital cameras capture the images with an electronic sensor called a CCD.
6.) Auto: The camera will completely control flash and exposure.
     Program: Unlike full auto mode, you can usually control flash and a few other camera settings.
7.) To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).
8.) To freeze motion, camera will use the highest shutter speed possible.
9.) faster camera response time
     more control over focus
     encourages better composition
10.) no flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.
11.) In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
12.) Too much light and the picture will be washed out
13.) Not enough light and the picture will be too dark
14.) A stop represents a relative change in the brightness of light.
15.) One
16.) Four
17.) The longer exposures ( like 1 second ) give much more light to the film than a 1/1000 of a second exposure
18.) It makes the photo darker
19.) The aperture on a camera controls light.
20.) Open up the aperture more. 

Camera Parts


Aperture- an opening, hole, or gap.
Shutter- a device that opens and closes to expose the film in a camera.
Exposure- the state of being exposed to contact with something.
Depth of Field- the distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.
F-Stop- the setting of an adjustable lens aperture, as indicated by an f number.
Focal Length- the distance from a focal point of a lens or mirror to the corresponding principal plane.
