Exposure Triangle Mastery Flashcards

Which combination is most likely to cause camera shake blur in a handheld shot?

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.

What happens to depth of field as you stop down your aperture from f/2 to f/16?

Answer: It increases

Stopping down to a smaller aperture (higher f-number) increases depth of field, bringing more of the scene into acceptable focus.

A sports photographer needs to freeze a fast athlete. Which exposure setting is the highest priority to adjust?

Answer: Shutter speed

Shutter speed directly controls motion freeze; a fast shutter like 1/1000s or higher is needed to stop athlete movement.

What is 'exposure reciprocity' in practical shooting terms?

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.

ISO 200 is how many stops more sensitive than ISO 100?

Answer: One stop

Doubling ISO (100→200) represents exactly one stop increase in sensor sensitivity.

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?

Answer: Raise ISO to 6400

Pushing ISO to 6400 significantly increases digital noise, degrading image quality more than the other options.

In the exposure triangle, which two elements directly affect the visual appearance of the image beyond just brightness?

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.
