https:\/\/youtu.be\/2CEJBSzn4YQ How To Use A Light Meter To Improve Your Video How To Use A Light Meter To Improve Your Video or How to Improve the Quality of Video Using a Light Meter. A light meter is used to measure the amount of light that is needed based on your setting. I have been contemplating purchasing this device to improve the quality of my video over a year now, and I finally got it. I enjoy it's easy to use functions and how quickly I can improve my videos. This meter has all the modes I need such as ISO, aperture, and shutter speed control. The instructions are straightforward and as long as you have a basic understanding of the exposure triangle. ISO, aperture and shutter speed, you will be using this light meter for 15 minutes once you quickly pour over the settings. This light meter allows you to read reflected light, suitable for landscape photography or reflective one-dimensional subjects as well as ambient light or to improve your lighting for video, used for 3-dimensional subjects. The Sekonic L-358 displays an f-stop range of f\/1.0 to f\/90.9, and a shutter speed range of 30-minutes to 1\/8000th-of-a-second (1\/1000th in Flash mode), both of which can be displayed in full-, half-, and third-stop intervals to mirror your camera's exposure display. When set to "full," the exposure is displayed in tenth-of-a-stop increments with a repeat accuracy of +\/- 0.1 EV.
