[FEATURE]: Implement TLCI / TLMF calculation #974
Comments
Hi @JarrettR, Thank you! I never heard about this metric, do you know if its usage is widespread? The most common ones being CRI, CFI/TM-30-18 and SSI. Cheers, Thomas |
I've seen it becoming more popular in recent years - Enough that the latest firmware update for the Sekonic C-7000 added it, along with TM-30 and SSI. I've attached an export CSV as an example. Specifically in film, people are starting to notice it. |
I second JarrettR. -Frank |
Description
TLCI-2012 is a similar measurement to CRI, with different swatches and an expanded algorithm.
TLMF-2013 is an additional algorithm that matches luminaire, given camera data. This one may be harder, as the user would need to supply this data.
The brief is here:

The software zip has a little bit of information, which expanded, along with all of the math, in the tech brief here:
