 +====== Simple Bump Map Texture ======
 +I ran a simple test using the same basic image on three panels, and three different techniques
 +to apply a texture:
 +  * Texture only
 +  * Texture with a Bump Map
 +  * Texture using Multiply node (something I saw in the 1st Cycles tutorial I watched and I wanted a comparison).
 +  ​
 +The results are pretty clear: the Bump Map technique works best.
 +===== Images =====
 +**Note:** If you download the source, the texture images are packed inside.
 +The texture file:\\
 +{{:​scode:​blender:​cycles:​avatar_movie_leather_texture_by_alexesn.jpg?​400| Texture File}}
 +The Bump Map:\\
 +{{:​scode:​blender:​cycles:​avatar_movie_leather_texture_by_alexesnbumpmap.jpg?​400|Bump Map}}
 +The results:\\
 +===== Source File =====
 +Includes the packed texture and bump map images!
 +{{ :​scode:​blender:​cycles:​bumpmap.rar |}}
 +===== Photoshop Bump Map =====
 +Creating a bump map image is easy. I used Photoshop CS2 because it's what I own. Feel free to use
 +your favorite editor!
 +  - *ckb Open the background/​texture image in Photoshop
 +  - *ckb Click Filter -> Blur -> Gaussian Blur and set the Radius to 1 pixels.
 +  - *ckb Click Image -> Adjustments -> Desaturate to make it black and white.
 +  - *ckb Save your slightly blurred, grayscale image as a PNG
