With my old camera, Canon 30D, everything is good. I used ColorChecker Passport to create my custom profiles. It works out great and I am happy. With the new 6D, the custom profile seems to give me a "greenish" cast. At first I thought the colorchecker was old and not working as well anymore. I bought a new one but the profile still gave me the same result. I took a photo of a scene including the graycard for white balance. I import the photo into Lightroom without any preset or adjustment. I choose the WB dropper to set the white balance for the photo under Adobe Standard Profile. For shady photo, I get temp around 7500 (give or take) and +10 tint. Everything looks great but the color is a little pink for my taste. Without changing anything, I switch the profile to Colorcheck custom profile. Everything has a heavy green cast now. Then I go back to the basic panel, and use the WB dropper on the gray card again. The photo looks good now; however, I got the temp around 10k and +80 to TINT level. That's way too high. I don't know if it's my camera problem or not. It has bugged me ever since. Also, now I cannot use the presets WB (cloudy, shade, daylight, etc...) any more when using the custom profile because those presets have very low TINT value in which my photo will look really green.
Thank you for your time.
