I'm a big Photoshop fan.  I've had it since version 4.  Allthough I've often wondered how many of Photoshop's functions can now be handled without leaving Poser's Material Room.

For instance I'd like to desaturate the Image_Map, in this screenshot; in order to then plug that into the Bump channel, of the PoserSurface.  My first instinct is to open Photoshop, desaturate, and create another map; but this takes time, and especially...RAM?

Likewise I am interested in knowing how to increase the amount of Saturation in an image.

I'm also wondering how to brighten/darken an image?  I understand how to increase/decrease the Difuse Color and/or Value of a material; but could this happen before the Poser Surface?

And now that I'm thinking of it, it would be nice to have a simple place to referance any/all Poser functions, that would save me time and RAM from Photoshop?  Like take Contrast, for example; is it possible to raise/lower an Image_Map's contrast, within Poser? 

I know some Photoshop functions would be very tuff, like Levels; and others would be a little obscure, like many Brush strokes.  But I'd still like a firm grip on when to think of opening Photoshop, and when to just add a node. 

So, if anyone has any questions and would like to ask here; or if you may just have a tip to add, please do so?  Any replies will be greatly appreciated!
