Post-processing nodes called imagers operate on pixels before the output driver. Imagers can be chained together.
It is possible to save Imagers chains in a Material Library. This makes it possible to share the library and reload the chains in any scene.

A video tutorial that shows how to use imagers can be found here.
The physical camera controls can coexist with other Arnold imagers. In that case, the physical camera controls apply at the very end, so after the other imagers, to preserve the look between the legacy Frame Buffer and the Arnold RenderView.
