Understanding Aperture

These two photos may be extremely random

but show a lot with understanding aperture.

 

 Small Depth of Field

ISO- 100

Aperture- f/5.6

Shutter Speed- 1/250

 

 

Large Depth of Field

ISO-1600

Aperture- f/36.0

Shutter Speed- 1/125



Measured in F-Stop, Aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the digital sensor. In the camera aperture effects the size of the hole that lets light in. The larger the hole the more light gets in and the smaller the hole the less light. As for visually in the photograph when more light is allowed in, there is a smaller F-Stop meaning the photograph will have a blurry background and the subject in focus. When there is a higher F-Stop less light enters making the whole photograph in focus. The exposure triangle relates to light and how it enters the camera and aperture is the hole where light enters.
