In this last chapter of the book and of the robot project, we will take look at the post‑production process in LuxRender. In other projects, the normal workflow for adjustments after the rendering would be aimed at some image editor such as GIMP. However, with LuxRender, we have another way to edit and fine-tune the image without the need of image editor software. In this chapter, we will learn how to make the necessary adjustments to the image inside LuxRender.
