Photography Exposure Triangle Mastery 3 — Questions and Answers
Question 1: Which combination is most likely to cause camera shake blur in a handheld shot?
- 1/500s, f/8, ISO 800
- 1/30s, f/2.8, ISO 3200 (Correct answer)
- 1/250s, f/5.6, ISO 400
- 1/125s, f/4, ISO 200
Correct answer: 1/30s, f/2.8, ISO 3200
1/30s is well below the safe handholding threshold for most focal lengths, making camera shake blur very likely.
Question 2: What happens to depth of field as you stop down your aperture from f/2 to f/16?
- It decreases
- It stays the same
- It increases (Correct answer)
- It only changes with focal length
Correct answer: It increases
Stopping down to a smaller aperture (higher f-number) increases depth of field, bringing more of the scene into acceptable focus.
Question 3: A sports photographer needs to freeze a fast athlete. Which exposure setting is the highest priority to adjust?
- ISO
- Aperture
- Shutter speed (Correct answer)
- White balance
Correct answer: Shutter speed
Shutter speed directly controls motion freeze; a fast shutter like 1/1000s or higher is needed to stop athlete movement.
Question 4: What is 'exposure reciprocity' in practical shooting terms?
- The relationship between color temperature and exposure
- Maintaining equivalent exposure by adjusting two or more triangle elements together (Correct answer)
- The reciprocal of the ISO value
- The inverse relationship between focal length and depth of field
Correct answer: Maintaining equivalent exposure by adjusting two or more triangle elements together
Exposure reciprocity means you can keep the same brightness by adjusting ISO, aperture, and shutter speed in complementary ways.
Question 5: ISO 200 is how many stops more sensitive than ISO 100?
- Half a stop
- One stop (Correct answer)
- Two stops
- Three stops
Correct answer: One stop
Doubling ISO (100→200) represents exactly one stop increase in sensor sensitivity.
Question 6: You shoot indoors at 1/60s, f/2.8, ISO 1600 and the image is still too dark. Which is the LEAST desirable fix for image quality?
- Add artificial lighting
- Use a faster lens (f/1.4)
- Raise ISO to 6400 (Correct answer)
- Use a tripod to allow slower shutter
Correct answer: Raise ISO to 6400
Pushing ISO to 6400 significantly increases digital noise, degrading image quality more than the other options.
Question 7: In the exposure triangle, which two elements directly affect the visual appearance of the image beyond just brightness?
- ISO and shutter speed
- Aperture and ISO
- Shutter speed and aperture (Correct answer)
- ISO and focal length
Correct answer: Shutter speed and aperture
Shutter speed affects motion blur and aperture affects depth of field — both change the look of the image, not just exposure.
