28 Lights Compared - Skintones and Light Spectra

CRI / TLCI ratings aren't enough to determine how a light performs. Studying the spectrum and actual tests are extremely helpful:

This is a test of how a Red Helium 8K's sensor responds to these lights. ARRI, Sony, Canon, Panasonic, Blackmagic etc. will have different color responses. I've found Canon and Sony to respond well to the Aputure and Fiilex lights for skintones (Dracast was OK in comparison). From this 28 light test it's clear that there are many lights which perform better (on the Red sensor and probably on Canon & Sony as well). It's also clear why the Sun, tungsten, HMI, and Kino's are so good with color (best/full spectrums => best skintones).
 
When I saw this last year, I did note that some of the lights did not look as good as they do on some of my cameras or some of the other cameras I've seen them on(and some were just fine). And a real world example for me, I bought a pair of the Intellytech 2x2 bi-color cloth panels and they don't look as good on my VariCam(in preset) as they do my F55(in preset). Haven't tried them on my original C300.

Much different world now than when it was just 'either tungsten or HMI' with a CCD Betacam or film.

Yeah, light tests would be most helpful if using an ARRI, Red, Sony, Canon, Panasonic, BM, etc. Which brings up the idea- based on light spectrum measurements, which lights will work best with which cameras. Would be a very helpful test! Generalizing further, using known light sources (including tungsten and perhaps HMI (full spectrum sources)) and shooting color charts, be able to accurately predict camera performance with specific lights based on e.g. Sekonic C-700 spectral measurements (+ very color neutral lenses).


* from current demos, would expect VENICE to be up there with Alexa for working well with many light sources, including mixed lighting.
 
I think it was Litegear showing off some lights earlier this year that are supposedly "tuned" and adjustable for optimal performance with different cameras/sensors.
