ISO & Gain

The Camera- ISO and Gain

1. What is ISO?
ISO is the setting that makes your photos brighter or darker. By increasing the ISO number, the picture becomes brighter.

2. What is the visual difference between low & high ISO?
High ISO images are much brighter, whereas low ISO images are darker.

3. When do you use a lower ISO? When do you use a higher ISO?
Low ISO is used when there is plenty of light, to minimize the appearance of noise as much as possible. High ISO is used to fight against motion blur and to pick up a sharper image.

4.Find visual examples of low & high ISO noise visibility.

  THE CAMERA-  APERTURE AND IRIS 1. What is aperture? Aperture is the opening of the camera lens through which light passes to enter the camera.  2.  How does it affect exposure? In large aperture, a lot of light passes through the camera lens, resulting in a brighter photograph. In small aperture, very little light enters the camera lens, resulting in a darker photograph. 3. How does it affect depth of field? A large aperture results in large amount of foreground and background blur, creating low depth of field. A small aperture results in small amount of background blur, creating greater depth of field. 4. How do you pick the right aperture for your scene?  The right aperture depends upon how much depth of field and exposure you desire in the picture. 5. Find visual examples of shallow & large depth of field (Internet) SHALOW DEPTH OF FIELD: LARGE DEPTH OF FIELD:
