- 1. Mid-term Exam Digital Photography - 2863
- 2. 1 & 2. Name the two types of shutters and explain how each works.
- 3. 3. What does an exposure “histogram” measure?
- 4. 4. True or False: An image that is overexposed will show most of the values registering at the right of the histogram.
- 5. 5. There are several types of built-in meters that calculate the exposure in different ways. One type is the averaging meter. Name at least one other type of meter.
- 6. 6. When shooting in RAW, should you adjust the camera for different white balance environments?
- 7. 7. What does the aperture do? A. It controls how much light reaches the sensor. B. It controls how long the shutter is open. C. It controls the depth of field. D. It controls the speed of the film. E. Both A and C. F. Both B and D.
- 8. 8. How was this photo probably taken?
- 9. 9. True or False: Moving the exposure compensation dial to +1 or +2 increases the exposure by one or two stops and lightens the picture.
- 10. 10. The number of pixels in an image is referred to as its _____________.
- 11. 11. Explain what makes an “average scene” as far as exposure conditions are concerned.
- 12. 12. An aperture of f/2.8 lets in: a. twice as much light b. half as much light as an aperture of f/4.
- 13. 13. The focal length of a lens affects the photograph in what two ways? • Amount of light and angle of view • Angle of view and magnification • Depth of field and magnification
- 14. 14. What is “White Balance?”
- 15. 15. True or False: • A small aperture has a shallow depth of field and a large aperture has a deep depth of field.
- 16. 16. An f/32 aperture has what size opening? A. Large B. Small C. Medium
- 17. 17. Apertures of the same number (like f/22) are not all the exact same size! Why not?
- 18. 18. True or False: An “incident-light meter” measures the amount of light falling on the meter itself.
- 19. 19. The built in meter in your camera is called “TTL .” What does this acronym stand for?
- 20. 20. In a histogram, the number equivalent for white is: a. 255 b. 128 c. 0
- 21. 21. What is a “gray card?”
- 22. 22. If you are ever in a landscape situation without a gray card, what can you meter that is close in value to a gray card?
- 23. 23. In this cutaway view of an SLR with a long lens, what is the space defined by the arrow called?
- 24. 24. When metering for situations where the subject is darker or lighter than the background, what is the technique you should use?
- 25. 25. A lens is called “fast”because: A. It takes very little time to focus. A. It can capture a greater depth of field in a longer period of time. C. The wide aperture allows for faster exposure times.
- 26. 26. What is “clipping?”
- 27. 27. When using a digital camera and you are forced to either overexpose or underexpose the photograph, which should you choose to do?
- 28. 28. What percent gray is a photographic gray card?
- 29. 29. A digital picture is made up of a large number of ________, each one a square with a single value and color in a grid like a checkerboard.
- 30. 30. True or False: The shorter the lens, the greater the depth of field.
- 31. 31. What are the two types of color processes? (One commonly uses the CMYK color environment and the other uses the RGB environment.)
- 32. 32. What is “bracketing?”
- 33. 33. What does the acronym “DSLR” stand for?
- 34. 34. Describe how this photo was taken.
- 35. 35. The quality of light is called color temperature and is measured on a scale in degrees ____________.
- 36. 36. A device that reads the amount of light striking your subject is called __________.
