Photography Exam Flashcards
What are the three manual controls of the camera?
Shutter Speed, Aperture, ISO
Setting that determines motion?
Shutter Speed- Shutter speed determines how long the exposure is. It is used to control motion. Fast shutter speeds are able to freeze motion. Slower shutter speeds can blur motion.
Shutter Speed (Stops)-Each variable represents a one stop change in shutter speed. 1 second is the slowest shutter speed that will appear on the exam and 1/1000th of a second is the fastest. There is a pattern where the number/fraction doubles/halves depending on whether the setting is speeding up or slowing down.
1 sec (slow)
1/2
1/4
1/8
1/15
1/30
1/60
1/125
1/250
1/500
1/1000 sec (fast)
If shutter speed is set at 1/15 and you speed up by two stops what will the new shutter speed be?
1/60 (1/15, then 1/30, then 1/60)
If shutter speed is at 1/250 and you slow down by 1 stop?
1/125 (half)
Setting that determines depth of field?
Aperture- The opening of the lens. Referred to as an f-stop. Aperture controls depth of field. A large aperture like f 1.4 will help produce a shallow depth of field while a small aperture like f22 will produce a longer depth of field. Think gauges on a piercing. Gauges with a smaller number means a bigger hole in the lens. Smaller numbers mean a smaller hole in the lens.
Aperture (Stops)-Each variable represents a one stop change in aperture. f/1 is the largest aperture that will appear on the exam and f/32 is the smallest. Remember that the smaller the number, the larger the aperture
f/1 (large)
f/1.4
f/2
f/2.8
f/4
f/5.6
f/8
f/11
f/16
f/22
f/32 (small)
If aperture is at f/11 and you close down by two stops, what is the new aperture?
f/22
If aperture is at f/5.6 and you open up by one stop, what is the new aperture?
f/4
Setting that determines noise/grain?
ISO-International Standards Organization - Refers to the camera’s (sensor’s) sensitivity to light. As ISO increases, so does the amount of noise/grain. Low ISO is 50 (least grain, rich), High ISO 6400 (tons of noise/grain)
ISO(Stops)-Each variable represents a one stop change in ISO. 6400 is the most sensitive to light and highest ISO that will appear on the exam. 50 is the least sensitive to light. ISO has a simple pattern of doubling or halving as you increase or decrease by one stop.
6400 (noise)
3200
1600
800
400
200
100
50 (rich)
If ISO is set at 400 and youincrease sensitivity by twostops, what is the new ISO?
1600 (400-then 800-then 1600)
What is a stop?
One stop represents the doubling or halving of light in relation to the camera’s exposure.
For example: opening from f 11 to f 8 doubles the light and is a full stop. Slowing down the shutter from 1/60th to 1/30th or increasing ISO from 400 to 800 are both examples of a one stop increase to light sensitivity
(= double the amount of light). Moving the opposite direction, closing down from f 8 to f 11cuts the light in half
The range or region of an imagethat appears in sharp focus?
Depth of Field-
The range or region of an image that appears in sharp focus is referring to depth of field. Depth of field is determined by several factors, aperture (f-stop) being most notable.
What does focal length determine?
Focal length determines the magnification of subject, andcompression between foreground and background.
