A text-based guide complementing a nine-part video tutorial series on compositing in Blender. The content focuses on utilizing the Depth (Z) pass to create atmospheric and aerial perspective effects in large environments. It covers techniques for creating distance-based masks from the camera to drive various visual adjustments. Effects demonstrated include distance blurring, blue shifting, desaturation, and contrast reduction. The guide also covers technical topics such as camera clipping, normalizing depth, creating compositing node groups, and using the Z-Combine node.
