Rock - Bump vs. normal map

[Marko]

Hi,
for a sports shoe outdoor scene I have to use rocks and trees.
Do get the rocks a little bit sexier I thought I could use the textur to bump node.
But the effect of the bump is not so good at my rock. In my opinon I do also not recognize remarkable changes while chanching the values in the F1-example-scene of the bump node.
Isn´t there a node to load a normal map in order to bring the structure of the rock into the front or does the bump node not work or is it my mistake?

The bumbmap helpscene should provide the info you will need i think.

I do feel that the bump node in the nodes F1 example does not bring a significant bump effect.
If I use the bump node like in the helpscene (with the specific rock texture in grey 0-255) I got this result:
