- What does a neutral density filter do?
- Contrast measures what in a print?
- Color systems divide all colors into which three measurements?
- Maximum depth of field at a given aperture is achieved by focusing at what?
- How would you define exposure in mathematical terms? (X times Y = exposure)
- a Intensity (aperture) x Time (shutter)
- b Absorbs equal quantities of all wavelengths of light. It allows you to use wider apertures or slower shutter speeds without changing color balance.
- c Hue, Luminance, Saturation
- d The difference between light and dark.
- e 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.
5 Multiple choice questions
- 1 or 2, depending on the lens, could be 2 to 3.
- Curves adjustment; Levels adjustment; Brighteness/Contrast adjustment
- Similar to a normal lens at about 30 degrees
5 True/False questions
The useable exposure range of a sensor, or the range of subject brightness is called what? → Bit
An 8x10 at 240 ppi will have a resolution of what? → A raster image
To minimize facial wrinkles, this type of lighting is best → Diffused front lighting
What kind of light will be produced when using a large white umbrella close to a subject? → flat, low contrast light
Why is depth of field greater on a short lens versus a long lens? → Relative aperture. The opening on a long lens must be larger than a corresponding opening on a short lens to produce the same f-stops.
