Lecture

• The Physical Camera is a digital representation of a real-world camera and all the terminology and rules of photography apply here as well
• You may start with discussing the basic settings of a camera
  • Aperture – how it’s measured and how going from one F-stop/F-number to the next affects the exposure
  • Shutter speed – different cameras use different ways to determine the speed of the shutter
    • Still cameras specify the shutter speed in seconds or fractions of a second
    • Cinematic cameras have a circular rotating shutter and the time the shutter is open is defined in degrees
    • In CG, we can also determine the shutter speed in frames
  • ISO – the sensor sensitivity directly affects the exposure. Higher values are need in dark conditions. Real-world sensors have an issue where using higher values for the ISO introduces noise into the image. This however is not the case in CG.
  • EV – exposure value allows us to keep a constant exposure while adjusting Aperture and Shutter Speed settings
  • Focal length affects the angle of view and is important when setting up the shot
  • White balance allows us to color correct the image to account for the color of the illumination
• Then you can move to the settings of the Physical Camera and relate its settings to each of the properties of real world cameras described previously

Demonstration

• In this cycle, you can use the provided scene and handout to demonstrate the settings of the Physical Camera

Activity

• In this cycle, you are going to let your students experiment with the provided scene. You may want to give them the provided handout to use as a guideline
