Spot Metering
Metering is the camera’s means to evaluate the light and shadow in a particular scene and adjust accordingly. In general, there are three main metering modes:
- Evaluative/ Matrix metering: This is where the entire frame is taken up for evaluation and the exposure is adjusted accordingly. Good for all round photography.
- Centre Weighted: Here a patch of the frame is used to evaluate the optimum exposure. It can generally be selected by the user for fine tuning.
- Spot Metering: This brings the area under consideration to a spot in the frame, which can be selected as per need. Very useful if the photograph is of the moon or something bright in a sea of darkness sort. Then the spot can be fixed on the bright bit and the metering can be adjusted accordingly.
It pays well to be adept at the metering modes and experimenting with them so that one can know what to use when.
The featured image of the post has been shot using spot metering, where the metering reference was the sun.
Last time, S was for Shutter Speed.
