Photography - Camera Functions

1. Aperture

   • Controls how much light enters the lens
   • affects depth of field
     • Wider aperture = shallow depth of field
     • Narrow Aperture = most or all the image will be in focus
       • In order to be in focus, need more light= longer exposure time
     • Wider Aperture = only a select portion of the image will be in focus.

2. Shutter Speed

   • How long/fast the lens is open
   • Leave the aperture open longer when shooting in low-light for better focus and depth of field.

3. ISO

   • How sensitive the light sensor in the camera is to light.
   • The higher the number, the more sensitive the camera.
   • Higher sensitivity can result in graininess and noise in the picture
