Understanding Camera Exposure Basics

What are the three components of the exposure triangle in photography?

• Shutter speed, white balance, ISO

• Shutter speed, aperture, ISO

• Aperture, white balance, ISO

• Shutter speed, aperture, white balance

Answer explanation

The exposure triangle in photography consists of shutter speed, aperture, and ISO. These three elements work together to control the exposure of an image, making the correct choice 'Shutter speed, aperture, ISO'.

Which component of the exposure triangle controls the duration for which the camera sensor is exposed to light?

• ISO

• Aperture

• Shutter speed

• White balance

Answer explanation

Shutter speed controls the duration the camera sensor is exposed to light. A faster shutter speed means less light hits the sensor for a shorter time, while a slower speed allows more light for a longer duration.

What effect does a fast shutter speed have on a moving subject?

• Blurs the subject

• Freezes the motion

• Increases depth of field

• Reduces noise

Answer explanation

A fast shutter speed captures a moment in time, effectively freezing the motion of a moving subject. This prevents motion blur, allowing for sharp images of fast action.

Which f-stop value represents a larger aperture opening?

• f/2.8

• f/8

• f/16

• f/22

Answer explanation

The f-stop value indicates the size of the aperture; a lower f-stop number means a larger opening. Therefore, f/2.8 represents a larger aperture compared to f/8, f/16, and f/22.

What is the primary effect of increasing the ISO setting on a camera?

• Increases depth of field

• Increases image noise

• Decreases shutter speed

• Decreases aperture size

Answer explanation

Increasing the ISO setting on a camera amplifies the sensor's sensitivity to light, which can lead to higher image noise. This is the primary effect, as it allows for better performance in low-light conditions but at the cost of image quality.

Which of the following is a typical ISO setting for shooting in bright daylight?

• ISO 100

• ISO 800

• ISO 1600

• ISO 3200

Answer explanation

ISO 100 is a typical setting for bright daylight as it allows for optimal exposure without overexposing the image. Higher ISO settings like 800, 1600, and 3200 are better suited for low-light conditions.

What is the relationship between aperture size and depth of field?

• Larger aperture, greater depth of field

• Smaller aperture, shallower depth of field

• Larger aperture, shallower depth of field

• Aperture size does not affect depth of field

Answer explanation

A larger aperture (smaller f-number) results in a shallower depth of field, meaning less of the scene is in focus. This is useful for isolating subjects from the background, making 'Larger aperture, shallower depth of field' the correct choice.

If a photo is overexposed, which of the following adjustments could help correct it?

• Increase ISO

• Open the aperture

• Increase shutter speed

• Decrease shutter speed

Answer explanation

To correct an overexposed photo, increasing the shutter speed reduces the amount of light hitting the sensor, making the image darker. Increasing ISO or opening the aperture would allow more light, worsening the overexposure.

What does the term "stop" refer to in photography?

• A unit of exposure

• A type of lens

• A camera mode

• A filter type

Answer explanation

In photography, a "stop" refers to a unit of exposure that indicates a doubling or halving of the amount of light that reaches the camera sensor. This term is essential for understanding exposure settings.

Which shutter speed is faster?

• 1/60

• 1/125

• 1/250

• 1/500

Answer explanation

The shutter speed indicates how long the camera's sensor is exposed to light. A faster shutter speed allows less light in, which is represented by a smaller fraction. Among the options, 1/500 is the fastest, allowing for quick motion capture.
