Light Metering

Q. I have a Nikon D3100 and I want to learn how to use the light meter to get the best out of my exposures? I tried looking online and could not find the information I needed. How to do use it and how to I access it on my Camera?

A. The internal metering works with three types: Matrix (all around metering), centre, and spot. Wherever your focus selection is, the camera will do its best to read the reflected light, and give an overall "good" exposure.
