Pop Quiz #1

How are you doing? Let’s have a pop quiz. Everybody loves those, right? Fun fun fun!

1. What’s another term for aperture?
   1. shutter speed
   2. f-stop
   3. ISO
   4. focal length
2. What three things determine the exposure of a photo?
   1. aperture, shutter speed, ISO
   2. shutter speed, ISO, metering mode
   3. aperture, f-stops, timer mode
   4. f-stop, metering mode, depth of field
3. Compared to f/8, f/16 is:
   1. a larger opening
   2. a smaller opening
   3. farther away
   4. blurrier
4. You’re taking a picture of your golden retriever Rex jumping to catch a frisbee. Which of these shutter speeds would best freeze the action?
   1. 1/50 sec
   2. 1/100 sec
   3. 1/500 sec
   4. 1/1000 sec
5. You’re taking a picture of a landscape. Which aperture would be best for getting all of it in focus?
   1. f/2
   2. f/4
   3. f/8
   4. f/16

Answers are below…

1. b, f-stop. The aperture, or f-stop, is the size of the opening
   in your lens.
2. a, aperture, shutter speed, ISO. Aperture is how wide the lens
   is open, shutter speed is how long the shutter is open, and ISO is
   how sensitive the sensor is.
3. b, a smaller opening. As f-stop numbers get larger, the
   aperture gets smaller.
4. d, 1/1000 sec. The faster the shutter speed, the better you will
   freeze Rex’s amazing leap mid-flight.
5. d, f/16. The smaller the aperture (i.e., the larger the number
   on the f-stop), the deeper your depth of field will be. With f/16 and slightly careful focusing, the grass in front of you will be as sharp as the mountains in the distance.

How did you do? If you got all five right, you’re well on your way to being an exposure ace. Congratulations!
