Jobs - The Camera Exchange

1. The lower the f-number, the _______ light the lens admits to the film.

(a) More

(b) Less

2. In program mode, the user selects the program and the camera sets both the aperture and the shutter speed.

(a) True

(b) False

3. One important advantage of an SLR is that the viewfinder shows what the lens sees.

(a) True

(b) False

4. To get the greatest possible depth of field, always choose the smallest opening consistent with the shutter speed.

(a) True

(b) False

5. Three of the following exposures are equivalent. Which one is different?

(a) f/8 @ 1/250

(b) f/2 @ 1/2000

(c) f/5.6 @ 1/250

(d) f/11 @ 1/60

6. What kind of filter is used to suppress reflections from a non-metallic surface?

(a) Polarizing

(b) Ultraviolet (UV)

(c) 1A (skylight)

(d) FL- D filter

7. Electronic flash is exceptionally good at stopping rapid motion because:

(a) It is very intense

(b) Its firing is synchronized with the shutter motion

(c) It fires for the same length of time the shutter is open

(d) It fires for a very brief time

8. Using the same f-stop, same subject distance, different focal lengths produce different depths of field.

(a) True

(b) False

9. Generally speaking, a high-speed lens (f/2.0 or faster) gives better optical performance at “moderate” apertures (f/4 - f/8) than a slower lens of the same focal length.

(a) True

(b) False

10. Extra-low-dispersion (ED) glass reduces which optical error of a lens?

(a) Chromatic aberration

(b) Distortion

(c) Coma

(d) Astigmatism

11. At a certain point (usually about f/8 or f/11), stopping a lens down further actually causes a loss of sharpness rather than an increase.

(a) True

(b) False

12. What are the three primary colors of light (the “additive” primaries)?

(a) Red, brown, yellow

(b) Green, red, brown

(c) Red, green, blue

(d) Blue, magenta, orange

13. Light directed toward the ceiling (or a side wall) and away from the subject is called:

(a) Front lighting

(b) Rembrandt lighting

(c) Backlighting

(d) Bounce lighting

14. The dynamic range of a digital system is:

(a) The amount of RAM available to process the image

(b) The number of colors available (i.e., 8 bit, 24 bit, etc.)

(c) The difference in grey values the system can reproduce

(d) The calibration setting on an RGB monitor

15. Exposure controls on DSLR/Mirrorless digital cameras are the same as film-based SLRs.

(a) True

(b) False

16. The physical size of some sensors is approximately the same size as 35mm film.

(a) True

(b) False
