This document discusses the key features and functions of a camera. It begins by defining a camera as an optical instrument used to take photographs or make films. It then explains the primary features that control a camera's functionality - focus, aperture, shutter speed, and ISO. Focus controls the sharpness of the image by adjusting the lens. Aperture regulates the size of the lens opening to control the amount of incoming light. Shutter speed determines how long the camera's shutter remains open during an exposure. And ISO specifies the light sensitivity of the image sensor, with higher ISO resulting in lower image quality.

2. What is a Camera ?
 The word camera comes
from a Greek word
camera obscura which
means “dark chamber”
 A camera is an optical
instrument for taking

4. FOCUS
 To see the image clearly is called a proper
focus.
 Focus in camera is basically is the
adjustment that is made to bring the desire
area or the desire part to the sharpest point
possible.

6. Aperture
 Aperture is the size of
the lens opening that
lets in more or less light .
 The smaller the
aperture number or F
stop the larger the
opening.
 Smaller aperture lenses
let in more light .They
are sometime called fast
lenses.

7. Shutter Speed
 The camera’s shutter speed
is a measurement of how
long its shutter remains
open as the picture is taken
.
 The slower the shutter
speed , the longer the
exposure time.
 The shutter speed and
aperture together control
the total amount of light
reaching the sensor.

9. ISO
 This setting on a camera which determines how
sensitive the image sensor is to light. HIGHER THE
ISO LOWER THE IMAGE QUALITY.
 LOWER THE ISO BETTER THE IMAGE
 IT IS ALSO CALLED FILM SPEED
