Camera Basics - Aperture

The video tutorial explains the concept of aperture in photography, comparing it to the human eye. It covers how aperture size, expressed in F-numbers, affects light entry and depth of field. The tutorial discusses lens specifications, emphasizing the importance of maximum aperture for lens speed. It differentiates between prime and zoom lenses, explaining variable apertures. The video also highlights how aperture influences ISO and shutter speed, and provides guidance on manual aperture adjustments using camera modes.

What is the role of the diaphragm in a camera lens?

• To focus the image

• To change the ISO settings

• To control the size of the aperture

• To adjust the zoom

How does a smaller F-stop number affect the aperture?

• It makes the aperture smaller

• It makes the aperture larger

• It has no effect on the aperture

• It closes the aperture completely

What is the effect of a large F-number on the depth of field?

• It brings both foreground and background into focus

• It only focuses on the foreground

• It blurs the entire image

• It isolates the background

Why are fast lenses preferred for night photography?

• They have a higher ISO setting

• They are lighter in weight

• They have a wider zoom range

• They allow more light into the camera

What is a characteristic of prime lenses?

• They have a fixed focal length

• They have a smaller maximum aperture

• They have a variable focal length

• They are always heavier than zoom lenses

How does a larger aperture affect shutter speed and ISO?

• It allows for a faster shutter speed and lower ISO

• It requires a faster shutter speed and higher ISO

• It requires a slower shutter speed and higher ISO

• It has no effect on shutter speed and ISO

What mode allows you to manually adjust aperture while the camera sets other parameters?

• Automatic mode

• Shutter priority mode

• Aperture priority mode

• Portrait mode
