 +====== Shadow Catcher ======
 +I wanted to create transparent images I could use as layers in Photoshop. The text and/or objects needed to cast shadows without visible planes.
 +  - *ckb Add your text and/or objects.
 +  - *ckb Add your "​shadow plane" to Blender.
 +    - *ckb Adjust to a size which will catch all of your shadows.
 +  - *ckb Object panel -> Cycles Settings:
 +    - *ckb Select the **Shadow Catcher** option.
 +  - *ckb Render panel -> Film:
 +    - *ckb Select the **Transparent** option.
 +  - *ckb Render your image.
 +There is no need to add a material to your shadow catcher plane! The plane will be rendered transparent,​ but with the shadows cast by other objects.

 +Imported into Photoshop with a solid red background. In Blender, I used a vertical plane, and a horizontal plane to show how the plane orientation can affect the results, cause by the shadows and camera perspective,​ when the object is made of a glass material: \\
