Light metering can be adjusted within your camera for particular situations.

In metering there are the terms of correct exposure, under exposed and over exposed.

Photographers always aiming for correct exposure. One can always bracket (i.e. take a series of different exposures and then choose the best exposure. This can also be achieved by using exposure compensation).

There are different metering systems on the camera

There are different metering systems on the camera

* multi zone metering

* multi zone metering

* spot metering

* spot metering

Multi zone metering is when the camera evaluates the whole image then decides the best exposure (this is the most commonly used setting, it is often used in landscape photography).

Centre-Weight average metering is when the camera calculates exposure based on the centre of the image (this is common in portrait photography). Spot metering is when a small select area in the image is used to calculate the overall exposure.

==Focusing==

==Focusing==

We have auto focus and manual focus. Auto focus does not work in every situation (situations where it could be a problem; in mono situations where the object and its surroundings are predominately one colour ie all shades of white, black, grey or any colour).

Single Shot AF is standard and locks onto the subject until you take the picture. AL Focus is used when you can follow a moving object with the camera with the shutter button pressed half way. At the desired moment you take the photo. The moving object will be in focus. AL Servo shot AF is a combination of the two.

== Depth of Field ==

 

The area of acceptable sharpness in a photo is know as “Depth of Field”. The Depth of Field is achieved through the size of the lens aperture. The aperture itself can be also be referred to as the iris which is the opening within the lens that the light travels through.

The flash intensity can be control on the flash itself although there are some that don’t.  The exposure can be also control with the aperture. The larger aperture, the more light enters the camera. This then results in a shallower depth of field.
