Q

How does shutter speed effect exposure

A

if the shutter speed is too fast, you’ll get an underexposed or too-dark image; if it’s too slow you’ll get on overexposed or too-bright image.

Q

How is shutter speed expressed

A

Shutter speeds are measured in seconds, or fractions of a second. For example, a shutter speed of 1/100 means 1/100th of a second, or 0.01 seconds. This is also known as the “exposure time”, because it’s the amount of time the sensor is exposed to

Q

What are the types of shutters

A
  • electronic shutters

- mechanical shutters (leaf shutter) (focal plane shutter)

18
Q

What affects the dof

A

aperture (f-stop), distance from the subject to the camera, and focal length of the lens on your camera.

19
Q

What is the rule of dof

A

The lower your f-number, the smaller your depth of field. Likewise, the higher your f-number, the larger your depth of field.

20
Q

What is hyperfocal distance

A

The hyperfocal distance is the closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp.
