How to Use a Light Meter in Photography
For decades, there’s a piece of gear that I’ve always had in my camera bag. This would be a handheld light meter. I feel I’m in the minority these days by still using a handheld light meter and that’s too bad this is so.
While one can certainly shoot using their in-camera meter, there are cases where it’s not the best choice or even feasible to do so. In this guide, we will cover everything from what a light meter is to how to properly use one in your photography.

A handheld light meter is a device that measures light in order to determine the correct exposure for photographing an object or scene.

No matter how the information is displayed, most photographic light meters will provide you with the same basic information. By measuring the available light, the meter will provide the correct aperture/f-stop combination for a given scene.
Now at this point you might think “My camera’s built-in meter can tell me that”, and that’s true, but is it going to be the most accurate and consistent? And what about studio flash?
