Chapter 5. Beyond Grading
This chapter deals with advanced compositing beyond grading. These techniques
emphasize alternate methods in Blender Compositing for some specific 3D render re-
quirements that can save lots of render time, thereby also saving budgets, in making
a CG film. Following is the list of contents that will be presented in this chapter:
• Relighting
• Fresnel effect in compositing
• Depth of Field and Bokeh
• Glares
• Motion and directional blur
• Lens distortions
• Grouping
• UV mapping
• Organizing nodes

As the final look of the frame is achieved during the compositing stage, there will al-
ways be numerous occasions where there is a requirement for more render passes to
finalize the image. This results in extra 3D renders, along with more time and money.
Also, few inevitable applications that give life to an image, such as lens effects (De-
focus, Glares, and motions blur), are render intensive. Blender Compositor provides
alternate procedures for these effects, without having to go back to 3D renders. A well
planned CG pipeline can always provide sufficient data to be able to use these tech-
niques during the compositing stage.
