Summary: 

A Spot Meter takes a meter reading from a specific part of a scene or subject and allows you to allows you to lock in the exposure.


What is the Camera Metering?
The camera meter is the technology of the camera that evaluates the subject that the camera is looking at and tell you if your photo is under exposed or over exposed. This is shown through the expose meter. However, sometimes, the photographer want a highly exposed photo to display an effect on an under exposed for a different effect. Example below.

Definition: 
ISO is the measurement of sensitivity of a digital camera's sensors is to light. The speed or light-sensitivity of a digital camera's sensor is rated in ISO numbers -- the lower the number, the slower the response to light. Example below.

Element 1 – Aperture and Depth of Field (DOF) - Photos

F-stop: f/5.6
Shutter Speed: 1/20
ISO: 100
Date: 17/3/16
This photo was used to focus on just the foreground

F-stop: f/9
Shutter Speed: 1/8
ISO: 100
Date: 17/3/16
This photo was used to focus on the foreground and some of the background













F-stop: f/25
Shutter Speed: 1/13
ISO: 1600
Date: 17/3/16
This photo was used to focus on both the foreground and background.

Definitions:
- Aperture: The control of how much light is received by the camera.
- Depth of Field (DoF): The selected zone of the camera that is in focus.


Summary:
The aperture can be used to control the brightness in a photo. Aperture works by controlling the lens making it big and small depending on what the aperture's set on. For example when you select a small aperture, the lens becomes larger, taking in most of the light, if the aperture is high, then the lens becomes smaller taking in less light. The lower the 'f stop' number is, the smaller the depth of field, meaning the camera will only focus on the front of the image (closest object to the camera lens) and the background will be blurred. Small 'f stop' numbers allow the lens to open wider, allowing more light to get in. Higher 'f stop' numbers have the opposite effect.

Definition:
The Shutter Speed is the unit of measurement on a DSLR Camera that determines how long the shutter remains open as the picture is taken.


Conclusion:
The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor. Example below:
