What is a light meter?
A light meter is a device used in both photography and cinematography to determine the perfect level of exposure of a subject or of a scene. The light meter measures the amount of lumens being radiated from the light source around the subject and the scenery needed to be photographed or filmed. This measurement then calculates the perfect settings, i.e aperture (F-stop) and shutter-speed, and sometimes your ISO, to take the photograph or shoot the scene and capture a perfect exposure shot.
Why use a light meter?
It is very rare to see a light meter being used in outdoor photography however it is wise to have one on any shoot, whether it be outdoors or in studio. It does not really matter if you have years of experience in your field of photography or film, a light meter is still an imperative tool to get your desired effect first time round. Granted, one of the biggest arguments in the photographic world is that you can mend all mistakes with post production, however a great photographer is not measured by his/her editing skills but by his/her ability to get the picture perfect out of camera shots. This applies to cinematography on an even bigger scale.
How to use a light meter
Using a light meter is not as difficult as it may seem. Once you have everything setup and your subject or scene is in front of your camera – hopefully placed on your tripod, take the light meter and depending on your model of light meter press the ‘get settings’ button and wait for the light meter to calculate your settings. Once you have the desired settings set your camera settings to the same on manual mode. Your camera should have a built in light meter but an external light meter works so much better and is far more accurate.
Let’s look at some of the best light meters of 2019:
1.Sekonic L-308S Flashmate Digital Incident, Reflected & Flash Light Meter

2. Dr.Meter LX1330B Digital Illuminance/Light Meter
