There are many ways to achieve good results ...
I like to respond:
photon collector:
Thank you for your offer, I´d like

No, my Oly E-M5 has no "Oly-colors".
NMF and Walt.Farrell:
As for color temperature adjustment - I dislike operating with a lot of equipment (e.g. datacolor or xrite), which I only use 3 to 5 times an then it`s more or less a dead investment. I therefore decided to create param. sets which adjust the Affinity colors to those which are shown in Oly workspace. So far it runs and all of my friends do not wonder about "wrong" colors (see above, I am week in color recognizing). Consequently, I am satisfied with my abobe mentioned formula (I use it in a spreadseet) and as an image has to reflect the original atmosphere of a real situation AND original colors, I don`t want to focus too close to measured temperature colors.
But: the different color temperatures of the same picture in my camera, in Oly workspace and in Affinity Photo led me to the above question/proposal in this forum:
1) Why does Oly workspace show a different color temperature compared with the c.-temperature given from the camera (<±100 K, question concerns more or less Olympus and not Affinity)?
2) Why do Affinity and Oly workspace show different c.-temperatures, though the source of information is one and the same (differences of several 100 K, but no systematic deviation can be recognized)?
The answers to these questions would help me to understand the kind of color temperature determination in Affinity and to improve my Affinity parameter sets to my camera`s original software (Oly workspace).
I`d be grateful for explanations.
