  1. Tungsten light is approximately what color temperature?
  2. When doing close-up work, what happens to the depth of field when the subject is closer to the lens?
  3. What color is opposite Red on the color wheel?
  4. What is a color profile?
  5. A lens set at f/4 admits how much more/less light than one set at f/2.8?
  1. a Cyan
  2. b 3200 Kelvin
  3. c Half as much light
  4. d It decreases. A 50mm lens at 12 inches and f/4 has a DOF of 1/16th of an inch. At f/11, it increases to only 1/2 an inch.
  5. e A mathematical translator assigned to each piece of equipment you use (they map one gamut to another; and the ICC (or International Color Consortium) profile is usually shipped by the equipment manufacturer).

5 Multiple choice questions

  1. 1 or 2
  2. A mirror and pentaprism

5 True/False questions

  1. Bit depth refers to what?Also called a gobo; it is a small panel usually mounted on a stand that shades some part of the subject or shields the lens from light that could cause flare


  2. What does "photomacrograph" or "macrophotograph" mean?Black (0)


  3. What is the CCD or CMOS sensor?The sensor that converts the image from analog to digital (1's and 0's) CCD=charge coupled device; CMOS=complementary metal-oxide semiconductor


  4. A color image with smooth gradiations requires at least what bit depth?A raster image


  5. When buying a lens hood, you should get it in what size relative to the lens?It should match the focal length. Too wide and it's inefficient; too narrow and it will vignette; most likely the vignette would occur with wide angle of 28mm and below.
