Doc/tut about using compositor with full sample option

Support Compositing and Post Processing

All is in the title, I’m looking Doc/tut about using compositor with full sample option.

There is sommething I cant get, do I need to rerender the full image after having composting it ?

And how to have a decent visual feedback ?

thx

When rendered it’s ok, but when saving images from compositor it’s ugly, cant get how it works …

<-- Here it’s a 3k image scaled down 50%.

There is the image rendered composite -->

Both are full sample renders, but one is just tweaked in compositor, and saved from there.

EDIT :

omg, shift-r
