lecture 3 23:48 The 4 Speeds 1. Film speed- the sensitivity of film stock to light (higher more sensitive, lower less  sensitive) lower speed will be more resolute or crisp but needs more light  2. Lens speed- the most amount of light that an aperture will let it. Measured in f-stops.  The entire range of f-stops that any given aperture can have Camera speed- how fast the film is moving through the camera, measured in frames per  second. Standard is 24 fps although you can increase or decrease that number.  Increase camera speed from standard projection puts it in slow motion. Vice versa puts  it in fast motion. Shutter speed- the length of time measured in fractions of a second that each individual  frame is exposed to light in the film gate. 2 factors that contribute to shutter speed-  camera speed and the angle of the shutter itself. These are all related: the 4 speeds- each step is a difference of one stop.
