This is a tricky lighting situation: the sky is bright, the cliff is dark, and the waterfall is right in between them. In order to capture all of the details, you need to understand how to use your light meter.
Metering is another word for the different ways you camera can ‘look at’ a scene and determine exposure. In this tutorial you will learn how to use light metering most effectively.
The different kinds of metering are:
Evaluative or Matrix Metering: A good default.
Center Weighted Metering: Useful when one part is significantly brighter than another.
Partial Metering: Useful for backlit scenes.
Spot Metering: Allows for the most flexibility.
