Understanding About Aperture in Simple
Steps
Aperture is the unit of measurement that describes the size of
the opening in the lens that can
be used to control the amount of
light reaching the digital sensor.
Size of Aperture – Large vs Small
Aperture
aperture
is a hole within a lens, light can pass through which to the camera body. aperture
is expressed in f-numbers (for example f/5.6). These f-numbers also known as “f-stops”.
("f" means focal ratio)
("f" means focal ratio)
They are 2 kinds of f-stops
1. Smaller f-stop
2.Larger the f-stop
Smaller f-stop
A smaller f-stop means a larger aperture, The
size of the circle represents the size of the lens aperture
For example, f/2.0 is Smaller than f/1.4.
minimum apertures (highest f-number)
Larger
the f-stop
A larger f-stop means a smaller aperture. maximum apertures (lowest f-number)
Typical ranges
of apertures
f-number is
square root of 2:
