blue shift, no bug, wish to disable about exposure-render HOT 3 OPEN

Let me rephrase: why is there an XYZ Space?

Hi Christophe,

The blue shift you mention happens because internally, ER uses the CIE XYZ 
color space.

You therefor have to convert your (I presume) RGB to XYZ using the color 
conversion functions.

Hi Thomas, thank you for your reply,


today I have a much better understanding of the colors in your renderer.

I just wanted to get rid of the blueshift which requires some searching in 
the color space to get an actual grey-scale image.

By the way, i find it very confusing that the conversion of rgb-xyz ist 
implemented multiple times and not only once in RGBtoXYZ and reverse.

I tried using some other conversion matrices but the result was allways red 
or blue shifted.

Eventually I scrapped the XYZ Space and just use RGB. As I mentioned, I do 
not see the point of the XYZ space, it just adds confusion.


Regards and again thank you for your reply,

Christoph
