How to composite render channels?

[Anonymous]

Hi there,

I have a hard time compositing my render channels in the right way so they look correct.
I rendered out a beauty and diffuse, ambient, specular,irradiance, reflection and refraction. I tried to composite the render channels so that they look the same as the beauty channel - without luck!
Unfortunately there is nothing to be found about it in the manual or in this forum.
Which blend modes need to be used and in which order? In my scene I used the mia_material.

Thanks for any help or hint!

Not sure if you are still having this problem but for whatever it is worth I am going to guess that you are having gamma correction issues.
