No, it's the texture as it was. But it might be a different map I once downloaded from somewhere, as I have 3 of them, the others hazier indeed. So you might want to enhance in PS anyway.
They are 2 different image maps indeed; one color, one I made greyscale and took through Pixplant to make a displacement/bumpmap of it. So the one saying 01_1_BU is the bumpmap, obviously.
Btw. I don't know if you're familiar with node working, but I recommend naming all nodes you use with an easy to understand cryptic title. When the number of nodes increases it might get too complicated even for yourself to understand what all the nodes do (if you have 20 power fractals for instance).
