Editing Textures in Photoshop CS3

I was wondering if anyone is using Photoshop CS3 to edit textures. I was able to import part of my mask into Photoshop as a 3ds. file but I don't see the texture, just a silhouette of my mask. I wanted to use Photoshop to edit my texture mostly because I am not satisfied with what I'm getting in blender, and CS3 has smart filters specifically for 3D editing. I never used it before and could use a little help getting started. Like the proper way to format blend file for import into Photoshop. Anyone?
