Equivalent Exposure Quiz

What is the relationship between aperture and shutter speed in equivalent exposure?

• Aperture and shutter speed have an inverse (opposite) relationship in equivalent exposure.

• Aperture and shutter speed have no relationship in equivalent exposure.

• Aperture and shutter speed have a direct relationship in equivalent exposure.

• Aperture affects color balance, not exposure.

How does ISO affect exposure in photography?

• ISO determines the color temperature of the photograph.

• ISO affects the depth of field in photography.

• ISO determines the shutter speed in photography.

• ISO amplifies the brightness of the light.

What is the exposure triangle in photography?

• The exposure triangle is the relationship between color balance, contrast, and saturation in photography.

• The exposure triangle is the relationship between white balance, exposure compensation, and image resolution in photography.

• The exposure triangle is the relationship between aperture, shutter speed, and ISO in photography that determines the exposure of a photograph.

• The exposure triangle is the relationship between lens focal length, sensor size, and image stabilization in photography.

Imagine Jackson, Daniel, and Arjun are on a photography adventure. Jackson just adjusted his camera's aperture one stop from f/8 to f/5.6. How should Daniel adjust the shutter speed on his camera to maintain equivalent exposure?

• Daniel must increase the shutter speed by 5.6 stops

• Daniel doesn't have to change the shutter speed

• Daniel must increase the shutter speed by one stop

• Daniel must decrease the shutter speed by one stop

Aiden, Elijah, and Kai are having a debate about photography. Aiden argues that if you decrease the ISO from 400 to 200, the exposure remains the same. Elijah thinks the exposure darkens by two stops. Kai believes the exposure darkens by one stop. Who is correct?

• Aiden: The exposure remains the same.

• Elijah: The exposure darkens by two stops.

• Kai: The exposure darkens by one stop.

• None of them are correct.

In the exposure triangle, which element controls the amount of light entering through the lens?

• aperture

• ISO

• shutter speed

• white balance

If you decrease the shutter speed by one stop, how should you adjust the aperture to maintain equivalent exposure?

• Increase the aperture by two stops.

• Keep the aperture the same.

• Decrease the aperture by one stop.

• Increase the aperture by one stop.

What is the relationship between ISO and noise in photography?

• ISO has no effect on noise in photography.

• Higher ISO settings reduce noise in the photograph.

• Higher ISO settings can introduce more noise in the photograph.

• Noise in photography is caused by shutter speed, not ISO.

Aiden, Isla, and James are photography enthusiasts. They are experimenting with their camera settings and stumbled upon a challenge. They are currently using an aperture of f/4,

@ 1/250s, and ISO is 200. Can you help them figure out which of the following are equivalent exposures?

• f/5.6, @1/250, ISO 400

• f/8 @1/60, ISO 100

• f/2 @ 1/500, ISO 200

• f/11 @ 1/500, ISO 200

What is a stop?

• A tool that keeps the camera from shaking

• When the camera won't focus

• A unit of measurement for exposure adjustments
