Hello friends !
I wrote a little tutorial about color matching with 3d objects and real photos. I used for that a sphere, which I photographed on the original location. And so, I could match my 3d materials, with the background image from my location, also the reflections.

But now, I would like to test color matching without any reference probes, and only in 2d.
And well, I have no clue how I could do that !?
As instance, I´ve rendered a 3d object with an alpha channel. And now I want to match this 3d object to my background image.
I´ve tried to find some tutorials, and some ways I could do that.
But wasn´t succesfull.
Thank you for every little help and suggestions,
bernhard
