I have spent some time working with the X-Rite Colorchecker Passport to produce camera profiles. I have had much exchange with X-Rite and watched Michelís video. For me, there are some strange things going on.
1. From what I have read, the hardware and software are supposed to make a profile for that particular camera shooting in that particular light.
2. I find from Michelís video, and other sources, that after jumping through all the profile making hoops, one must then also set the white balance in the application (Lightroom, etc.).
3. In the video, that white balance was set by using the eye dropper on the appropriate square on the Passport on the same image which generated the profile in the first place.
I also watched Micheal's video on the LL video journal, and the result he obtained with the Passport profile was much better than the results without it, but I wondered if similar results could have been obtained by shooting a Whibal or similar reference card to set the white point in Lightroom, without making a custom profile. I suppose, the results would vary with the lighting. With lighting conforming to black body spectra, I would think that the Whibal would work well, whereas the Passport profile would have an advantage with nonstandard illumination. In Micheal's shoot the light could have been filtered by the surrounding vegetation.
