Great, I started the same but switched to calc the specified camera log output. Hence, you need to calc the linear reflectance "OUT" of camera Luminance "IN". The STOPS are given by STOPS = -log2(0.18/OUT). Then at STOP = 0 you have mid-gray (18%). In an "IN" range of 0-1 you gain STOPS between somehow -10 to 10.
@@cnomadic The problem is that I fear to infringe Ed Lachman's patent. I wrote a DCTL based on gamma transforms coming from Github - search: open-display-transfer > utilities > LogConvert. Simplify it for Luminance, then you only need to add the STOP calculation like described above; define the STOP-zones with RGB colors and it's done.
@ yes I saw a similar technique on RUclips and he did have to remove the code from his description for violating copyright laws. It’s just a bummer that his system is not broadly available . Even as a LUT purchase on his site. I would’ve paid for it.
Thankyou for the tips! I made one for myself using a similar methods but you went the extra mile. That plug-in looks super handy! How have you been finding the lut on set? It’s helped me so much!
@nomousego3825 yes the plugin made it very easy! I love how quickly the LUT allows me to check contrast ratios on set. Especially in uncontrolled environment, just to make sure I maintain consistency.

That’s amazing! Will you be posting your process?

@@tidatida4145 Could you explain in more detail, in simple terms for a non-technical person, what needs to be done after using LogConvert?
