This is a very simple tutorial. I'll show you how to increase the expressiveness of textures, to make them deeper.
1. Create new document; RGB; 72 dpi
2. Double click on layer for unlock it, name it organic.
3. Now set your background/foreground colors like me. We will use gradient tools later so let's do it now.
4. We will create our nice organic texture totally with layer styles. So, go to Layer: Bevel and Emboss and just use my settings.
