Understanding Aperture and Shutter Speed

Usual shutter speed for a still object?

• 1/5

• 1/60

• 1/180

• 1/focal length

Answer explanation

Use 1/focal length for still objects!

(Or whatever is closest).

So, for a 50mm focal length, you would use 1/45 as 1/50 does not exist.

What is aperture and how is it measured?

• Lens opening, measured in f-stops.

• A camera’s shutter speed control.

• The zoom capability of a lens.

• The sensor size of a camera.

Answer explanation

Shutter speed control is shutter speed

Zoom capability is zoom (prime is no zoom)

Sensor size is either Full Frame, APS-C, Micro 4/3, or Medium Format.

How does a wide aperture (low f-stop) affect an image?

• Changes the color of light.

• Less light, sharper background.

• Reduces the camera’s zoom.

• More light, blurry background.

What is the difference between a wide aperture and a narrow aperture?

• Wide aperture sharpens the background.

• Affects lens durability and size.

• Light amount and focus depth.

• Narrow aperture increases shutter speed.

What does high ISO cause, and why should you avoid it?

• Grain, darker image

• Blur, blurry image.

• Grain, bad image quality

• Noise, bad image quality

What do you change in daylight?

• Shutter Speed

• Aperture

• ISO

What do you increase when dark?

• Shutter speed

• Aperture

• ISO

Does exposure compensate for shutter speed and aperture?

• Yes

• No

What is the “correct” exposure for an image?

• The subject is visible

• It captures a high dynamic range

• The subject is in focus

• Jeremy is in it

What 3 variables in the camera / lens can you change to manipulate exposure?

• Aperture, Shutter speed and ISO

• Focal length, shutter speed, and resolution

• Aperture, motion blur, and shooting mode

• 1. Black point, aperture and focal length
