diving into ISO differences on the arri alexa mini LF which is technically an exposure index. Every camera is different so do your own tests, and remember, none of this will make or break an image. You can get a cinematic look without worrying about any of this. this is just a deeper look at the technical.
as you change the iso or EI on an arri alexa, you can redistribute the dynamic range. some other cameras behave like this, and some do not. a sony FX3 for example also has an exposure index, or EI when shooting in cineEI mode. this will adjust what you see on the monitor and not the recorded image. this is just a different way to expose an image and not a bad thing. the EI on the sony cine cameras, like the sony FX3 behaves like stop reduction LUTs explained here in this video.
hit me up with questions! more to come!
