Definitions of camera skills:

• Focus Control– Focus is the one area that lenses out perform the human eye. Lenses come in a wide variety of focal lengths, allowing them to “see” objects that are very large and very far away, like galaxies and stars, or objects that are very small and very nearby, like bacteria and DNA.

• Depth of Field- the distance between the nearest and the furthest objects giving a focused image.

• Focal length– the distance between the centre of a lens or curved mirror and its focus.

• White Balance– the colour balance of the image

• ISO– measures the sensitivity of the image sensor

• Aperture– a space through which light passes in an optical or photographic instrument, especially the variable opening by which light enters a camera.
