Description

Today I've started shooting with a Pentax K-5. The wb of my camera probably fails and I've tried to change it using a "spot" measurement. The temperature cursor jumped to 25000K which seems to me too much.

Attached one of the pictures

I can confirm that there is something wrong going on here.
In particular, the XYZ_to_temperature() in src/iop/temperature.c fails to bisect the temperature.

But right now i'm failing to understand what the problem is.
