I put up a thread in the Color Grading thread, but perhaps since the question deals with the Sekonic color meter it may be better suited for this section (not sure).
The Sekonic C-500 color meter gives "CC" index readings (meg/grn axis adjustments)
The CC index number multiplied by 2.5 directly correlates to a specific Color Correction filter number
aka 2M = Lee CC05M gel
OK, ...but how does that meg/grn adjustment number relate to the +/- 150 value in many applications (lightroom/resolve)?
Thanks in advance. Please see my other post for more details and a hypothetical situation that may warrant this use.
