The camera lens houses the Aperture.
This is basically the hole inside the lens which you can increase or decrease to let in more or less light.
Like your pupil!
Aperture (ƒ/Stop) numbers are indicated by an ‘ƒ’ in front of a number.
ƒ1, ƒ1.4, ƒ2, ƒ2.8, ƒ4, ƒ5.6, ƒ8, ƒ11, ƒ16, ƒ22, ƒ32
ƒ stands for ‘ratio of the lens focal length to the diameter of the entrance’
The aperture (ƒ/Stop) controls 2 things:
> the amount of light that reaches the film or digital chip.
> the Depth of Field.
The Depth of Field is a measure of how much ‘depth’ of an image will be in focus.
There are three things which can change the depth of field:
1. The aperture
2. The focal length of the lens used
3. How near the subject focused on is to the camera
There a 3 types of extreme settings using Depth of Field:
1. HYPERFOCAL
2. SELECTIVE FOCUS
3. BOKEH
