Because we like our exposure to be precise, we decided to upgrade our light meter to the Sekonic L-758CINE-U DigitalMaster. With a range of cine and video settings we can now make sure our lights are exactly where they should be. One of the huge benefits this meter provides, is it's ability to match the dynamic range to our specific camera, which can be a huge difference with the outcome of our video. With an ISO range of 3 to 8,000 in 1/3 steps and 17 other custom settings, we no longer have to guess how our camera will read the light.
