- Tungsten light is approximately what color temperature?
- When doing close-up work, what happens to the depth of field when the subject is closer to the lens?
- What color is opposite Red on the color wheel?
- What is a color profile?
- A lens set at f/4 admits how much more/less light than one set at f/2.8?
- a Cyan
- b 3200 Kelvin
- c Half as much light
- 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.
- 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 or 2
- A mirror and pentaprism
- The intensity of the illumination is inversely proportional to the square of the distance from light to subject. At twice the distance from the subject, the light illuminates only 1/4 of the original.
5 True/False questions
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
What does "photomacrograph" or "macrophotograph" mean? → Black (0)
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
A color image with smooth gradiations requires at least what bit depth? → A raster image
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.
