This is a quick under/over exposure test that I did with the Alexa Mini LF. The whole purpose of a test like this is to see how much flexibility we have with various exposures. If you are shooting something that is 5 stops under or overexposed you have probably chosen the wrong occupation!
Tests like these have nothing to do with total dynamic range because we are testing to see the camera's Useable Exposure Lattitude. There is a big difference between the two. We will have another post soon that will be entitled Understanding Exposure Tests.
