5 True/False questions

  1. The useable exposure range of a sensor, or the range of subject brightness is called what?dynamic range (not to be confused with gamut)


  2. If you must move to reduce the amount of flash reaching your subject, how far do you move?To create a 1-stop difference, multiply the original distance by 1.4. Example - if you were originally 5 feet away, a 1-stop difference would have you step back to 7 feet.


  3. If you're working with an automatic camera and you set the shutter speed and the camera sets the aperture, what mode are you working in?Infrared


  4. The quantity of light that reaches your sensor is controlled by what?Aperture


  5. Maximum depth of field at a given aperture is achieved by focusing at what?Hyperfocal distance. A lens focused at the hyperfocal distance has depth of field extending from approximately half the hyperfocal distance to infinity, whereas a lens focused at infinity has a depth of field only at infinity.
