'''Photography''' is the [[art]] or procedure of creating pictures or images by the action of radiant energy (typically visible light) on a sensitive surface such as reactive film.  While black and white is still a popular photography choice, today's digital and film photographs are primarily shot in colour. The word photography comes from Greek words and means “drawing with light.”

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).

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==

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).
