cycles GI multiply on paper

Is there a way to multiply(increase) cycles Global lighting bounces? like increase their strength? i Need to render paper and paper has way of reflect light more intense. just maybe there is some special material for paper, or maybe someone know how to make material bounce light more intense? i followed this example http://www.youtube.com/watch?v=dNoSWVu2Jvw
please help i would even buy material shader if someone would create it :slight_smile:
any help would do!
thank you very much!

Camera ray -> diffuse output… plug that into a colour mix node factor, first input into colour mix node is your normal paper texture, second input is white… change mix node factor to add… if its too bright, change the second inputs value

thank you is Camera ray -> diffuse output in material nodes?

Add node > Inputs > Light Path

Thinking you may be going about this the wrong way though… nothing reflects back more light than it receives, and forcing a material to do so will result in fireflies that will likely never converge.
