If things were not complicated enough already when it comes to exposing your image, along comes RAW & log to throw another wrench into the system. And that is why in this video I’m going to help you better understand how to get proper exposure when using a camera that shoots in RAW or in log.
Remember everything I taught you about IRE values and where things should fall on the waveform monitor? Well when it comes to shooting with a camera that records in log, you have to throw all that information out the window. And the reason why is because when camera manufactures use log values to record the images, they end up remapping tone values to different IRE values. And to complicate the matter more, each manufacture does it a bit differently. For example, Canon has decided to map their mid-tone value to 33 IRE, and Sony has decided to map their mid tone value to 38 IRE. So I can’t give you one rule that will work for all cameras. Which is why you have to end up reading the white papers that get published by different camera manufactures, or you have to do your own testing if those numbers are not published.
But lets take a look at one example so that you can see what is going on here. I am going to use Canon’s C-log as the example here.…
