How is aperture expressed in photography?
In f-numbers
In ISO values
In shutter speeds
In focal lengths
What does a larger aperture (smaller f-stop) mean?
More light enters the camera
Less light enters the camera
A larger depth of field
A smaller depth of field
What is the maximum aperture of a lens?
The smallest f-number
The largest f-number
The speed of the lens
The minimum aperture
Why are lenses with larger maximum apertures considered fast lenses?
They can pass more light into the camera
They have a smaller depth of field
They have a larger focal length
They have a faster shutter speed
What is the impact of aperture on the depth of field?
A large aperture brings all foreground and background objects into focus
A small aperture isolates either the foreground or background objects
A large aperture makes everything blurry
A small aperture sharpens out-of-focus areas
What is the advantage of using a fast lens in night photography?
