Need help with compositing.

Hi.

I’d like to get help with this simple compositing setup.
I’m tryng to paste a simple image as backround of my scene,but no luck at all,what i am doing wrong?
I don’t wan’t to use environment map,because the image will loose quality.



Blend file attached.

And second problem is,how do i use only light values from that picture,but still keep my lightning setup to lit up my scene?
Many thanks in advance!

Your render needs a transparent background (enable Transparent in the Render / Film settings)

With this setup you won’t get any distortion of the background due to the glass, you would need the background image to be part of the scene render

Depending of course partly on how realistic that glass-effect actually needs to be in order to “sell the shot.” In a pinch you could stick a label on it. :wink:
