A photographer wants to capture a moving car at night with minimal noise. Which settings should they prioritize?
High ISO, slow shutter speed
Low ISO, fast shutter speed, wide aperture
High ISO, fast shutter speed, narrow aperture

If you increase the ISO, what adjustment might you need to make to the aperture or shutter speed to maintain the same exposure?
Use a slower shutter speed or smaller aperture
Use a faster shutter speed or smaller aperture
Use a slower shutter speed or larger aperture
Use a faster shutter speed or larger aperture
Which scenario would most likely require a higher ISO setting?
Shooting outdoors in bright sunlight
Shooting indoors in low light without a flash

You are photographing a dimly lit concert. You want to avoid blurry images due to movement. What is the best strategy using the exposure triangle?
Use a slow shutter speed and low ISO
Use a fast shutter speed and high ISO
Use a wide aperture and low ISO
Use a narrow aperture and slow shutter speed
A student notices their night photos are very grainy. What steps can they take to reduce noise while maintaining proper exposure?
Lower ISO and use a slower shutter speed or wider aperture
Increase ISO and use a faster shutter speed
Use a narrow aperture and fast shutter speed
Lower ISO and use a narrow aperture
You want to photograph a fast-moving subject in low light with minimal noise. Which exposure triangle adjustments should you make, and what trade-offs are involved?
Use high ISO, fast shutter speed, wide aperture; trade-off is increased noise
Use low ISO, slow shutter speed, narrow aperture; trade-off is motion blur
Use low ISO, fast shutter speed, wide aperture; trade-off is shallow depth of field
Use high ISO, slow shutter speed, wide aperture; trade-off is motion blur and noise
A photographer wants to shoot a landscape with maximum sharpness and minimal noise. How should they set the exposure triangle?
Low ISO, narrow aperture, slow shutter speed
High ISO, wide aperture, fast shutter speed
Low ISO, wide aperture, fast shutter speed
High ISO, narrow aperture, slow shutter speed
You are shooting indoors without a tripod and want to avoid camera shake. How can you balance ISO, aperture, and shutter speed to get a sharp image with acceptable noise?
Increase ISO, open aperture, use faster shutter speed
Decrease ISO, close aperture, use slower shutter speed
Increase ISO, close aperture, use slower shutter speed
Decrease ISO, open aperture, use slower shutter speed
A student wants to take a photo in low light with minimal noise but does not want to use a flash. What is the best approach using the exposure triangle?
Use the lowest ISO possible, widest aperture, and slowest shutter speed they can handhold
Use the highest ISO possible, narrowest aperture, and fastest shutter speed
Use medium ISO, medium aperture, and medium shutter speed
Use the lowest ISO possible, narrowest aperture, and fastest shutter speed
You are photographing a sports event indoors. The lighting is poor, and you want to capture sharp images of moving athletes. What exposure triangle settings should you use, and what is the likely result?
High ISO, fast shutter speed, wide aperture; result is sharp images with some noise
Low ISO, slow shutter speed, narrow aperture; result is blurry images with minimal noise
High ISO, slow shutter speed, wide aperture; result is sharp images with minimal noise
Low ISO, fast shutter speed, wide aperture; result is sharp images with minimal noise
