Aperture
The aperture is the hole created in the lens, which allows the passage of light. This is also known as the f number. The lower the f number the bigger the light hole is and the higher the f number the small the light hole will be. Changing the aperture can have several interesting effects on the photograph. The wider the aperture (lower number) means that you can take photography’s in slightly darker lighting conditions. It also has the effect of creating a shallow dept of field where only the many subject is in focus and the foreground and background are blurred on purpose, this effect is known as bokeh where when using a small aperture there needs to be more light to be able to take the photograph. But all off this photograph will be in focus. If you increase the aperture the decrease the shutter speed.
