EXPOSURE TRIANGLE

The exposure triangle is composed of three aspects that relate to light and how it enters and interacts with the camera.

The three elements are:

1. Shutter speed 

• the amount of time that the shutter is open
• it also controls the light
• controls the ambient light

     2. Aperture

• another term for hole that controls the light
• the number of aperture denotes the vision
• the bigger the number the smaller the hole
• controls the depth of field
• is in the lens not in the camera

     3. ISO

• controls the light of the subject or image
• higher ISO the brighter the image & vice versa
• higher ISO speeds image noise
