Photoshop and Normal Maps

To make the textures I use, I use the image manipulator programme called (Photoshop) to make some called a Normal Map to make my textures even more detailed.
To make a long story short. Normal Mapping is a design technique used to manipulate the lighting and dents in textures. In other words, it makes the lighting and detailed parts in textures more visible and more detailed.

I have created a simple test to see how normal maps will effect the image, and how it exactly brings out the more detailed parts in textures.
