[Spot] : Only the rectangular area in the centre of the LCD monitor will be metered for light. This is suitable when the subject in the

centre is exposed correctly, regardless of the back lighting.

If the subject is not the centre of the focus area, do not use the spot metering as this may result in an exposure error. In this circumstance, it is better to use exposure compensation.
