PPT-Camera ISO, Aperture, & Lens

ISO Generally defined ISO is the cameras sensitivity to light If the camera has a low ISO the camera will be less sensitive to the light coming in If the camera has a high ISO it will be extremely sensitive to light ISO settings are as follows 100 200 400 800 and 1600. Understanding the relationship between three critically important parameters: the ISO speed, aperture (or f-stop number), and shutter speed. . Definitions-.

Made of high grade plastic or metal, this holds all the other parts together as well as provide protection to the delicate internal parts of the camera. . 2. Lens Assembly . This consists of several layers of lenses of varying properties providing zoom, focusing, and distortion correction. These lenses are mechanically interconnected and adjustment is controlled electronically by the camera's body. .
