I have seen a few books here and there mentioned. Such as "d'artiste: Digital painting" (but couldn't figure out if this book just pertained to making nice photoshop pictures or?). "Mastering 3d Texturing." "Surfaces : Visual Research for Artists, Architects, and Designer." "Texturing and Modeling" (by Ebert). Photoshop Textures Magic (by London). Digital Texturing and Painting (by Demers).
Thank you in advance for your time.
