Strange default WB settings in Color Calibration

So after getting to edit my Z5 ii’s photos I noticed that WB is set in a very strange way. I shot the photo with unmodified cloudy preset. What does this mean?

It simply means that the calculated CCT (correlated color temperature) doesn’t fall on the planckian or daylight locus, so you get the hue/chroma controls. That’s also why it says (invalid), by the way.

Here’s how the initial parameters are calculated:

Then, the default parameters of the color calibration will:

1. read the raw EXIF to fetch the scene white balance set by the camera,
2. adjust this setting with the reference white balance used in white balance module,
3. adjust this setting again with the input color profile in use (only the standard matrix).

The rest of that post is worth reading, as well.

I’m used to seeing Planckian (Black Body) with a slider for temperature.

Was that with the same camera and WB settings? If not, it’s to be expected that CC will arrive at different values, since both the D65 matrix and the “cloudy” WB value are likely not the same.

@Vente

When I set WB to “as shot” and reset CC, it switches to this:

I don’t know why, but for some reason resetting the module will always give different parameters (and look).
