Hello!

I am looking to create a technical viewing LUT within Lightspace CMS. I am trying to create a LUT that I can use on Alexa that pulls information by one stop exactly so I can view instantly what it will look like when the information is pulled one stop. e.g. shooting t/2.8 while in post will be pulling to t/4 to obtain more shadow detail --

I have tried to make this LUT and have not been able to achieve this --
rec709: https://imgur.com/4JYTKn8
-1 stop from lightspace cms: https://imgur.com/1MLY8OK

My process has been the source being arri alexa EI800 and pull -1. the destination being rec709

I am curious about this process and what I may be doing wrong since the LUT in arri color tool looks around 4 stops under etc.

What is the source image?
What other settings are you using in the Camera Options?

I mean what image are you applying the LUT to?
And what are the other settings within the Camera options.
