Basic Of Camera

1. KIND OF CAMERA SYSTEMS

Q. How many kind of camera?

A. There are two kind of cameras; Analog Camera and Digital Camera.

•Analog Camera: It is the type of camera that capture image on film.

Analog camera is made of three elements.

- Optical (lens)

- Chemical (Film)

- Mechanical (Camera Body)

•Digital Camera: Is a camera that capture image and store image digitally.

it made by three elements.

- Optical (lens)

- Mechanical (Camera body)

-Storage (Memory)

3. EXPOSURE DEFINITION

A photograph's exposure determines how light or dark an image will appear when it's been captured by your camera. this is determined by just three camera settings: aperture, ISO and shutter speed (the "exposure triangle"). Mastering their use is an essential part of developing an intuition for photography.

3.1 APERTURE

Aperture is a Function that used to controls the amount of light that entering into the Camera and make Dept of Field. We use Aperture Depend on the light condition.

Aperture is measured by F-stop (F/2.0, F/6.5….) . If you scroll up the number of F-stop the light that entering into the Camera was decrease.

Note:

- Aperture gives you lovely soft focus background or make sure that

everything are in focus, this call Depth Of Field (DOF).

- Shallow Depth of Field is meaning that soft focus background.

- Large / Deep Depth of Field is meaning that everything are in focus

from foreground to background.

COMPARATION OF WIDE&SHALLOW DEPTH OF FIELD

3.2 SHUTTER SPEED

Shutter Speed is the amount of time each individual frame is exposed for. Shutter Speed is used for control the speed and duration of the light that entering in to the image sensor, It also make the Motion Blur.

3.3 ISO

ISO is a function in the Camera that determines how sensitive your Camera is to light. If we take the photo with high light condition we should use the low ISO setting . If the low light condition we should use the high ISO setting. When we increase the number of ISO it mean that the lights are increase too.

Notes: when we use more large ISO setting it offer the lower quality of picture.
