Cameras!

^^

today randomly surfing AGAIN!^^

let's take a peek at today's treasure.

2 types of camera-

SLR cameras

point-and-shoot cameras

This is the "organs" of a SLR camera.^^

These are the "procedures" a camera take to shoot a picture.^^

1.when you click the shutter button, the camera quickly switches the mirror out of the way

2.screen turns black because the light is directed to the exposed film

In this sort of camera, the mirror and the translucent screen are set up so they present the real image exactly as it will appear on the film. The advantage of this design is that you can adjust the focus and compose the scene so you get exactly the picture you want. For this reason, professional photographers typically use SLR cameras.

cameras are built with both manual and automatic controls, and most point-and-shoot cameras are fully automatic. Conceptually, automatic cameras are pretty much the same as fully manual models, but everything is controlled by a central microprocessor instead of the user. The central microprocessor receives information from the autofocus system and the light meter. Then it activates several small motors, which adjust the lens and open and close the "thing covering the lenses of a camera"

Very Advanced and chim...TT
