I am trying to use ZBrush the way I would use Photoshop, to paint a 2D picture. By painting in layers and meshing the layers together as I go by using multiply, screen, blend, etc…Anyone know how I could do this using ZBrush? I did a quick search and came up empty, any help would greatly be appreciated. Thank you in advance.
… Bake , Blend, layers between them
Else you have “Custom Filters” (Convolution matrix) in the Tool palette for apply
Original Cameyo Tut Custom Filters
your own regulates for transform your image
Hope this help:)

I tried creating two layers then blending them together but I could not see a difference. I might be doing something wrong, care to give a quick step by step on blending? Thanks again.
…when the “Bake” button is pressed
Explanation is writing when you move your mouse over any Button or Icone with Ctrl pressed
It’s the “help on line” 
You will seen that you describ is right and the explanation
Ok, thanks man I will play around with it:)
It’s working, but I have one last question. How do you adjust the transparency of the layer’s? For example if you paint something with the material being transparent then once your done painting you wish to increase the transparency of what you just painted, how would you do that?
…is some curious in Zb 
You have 2 methods
One : Classical just paint with a less RGB intensity
Two : A real transparency : you need 2 Layers !
(see over the Button “Flatten” + Ctrl) in the Render menu
And see this tut by Pixolator
The catch is that layers don’t work the same way in ZBrush that they do in Photoshop, and this is because ZBrush is a 2.5D program whereas Photoshop is a 2D program.
In Photoshop, each layer rests entirely on top of the one blow it in the list. This allows effects such as Multiply, Dodge, Soft Light, Difference, etc. because the filter layer can look at the layers below it to see how it should behave.
In ZBrush, each layer is a parallel universe containing the entire width, height AND depth of the canvas. As such, they exist more for organizational purposes. It’s not possible for one layer to look at what’s below it because there isn’t really a “below” to begin with.
ZAppLink changes all of this a little bit in that it lets you send your canvas to Photoshop and edit it there. While in Photoshop you can perform layer effects, add text, use the various Photoshop filters, etc. When done, ZBrush will then incorporate your changes directly into the canvas.
Thanks for the reply guys, I appreciate the explanation on ZB functionality.
