This document focuses on techniques to enhance depth perception in virtual images through concepts like stereo vision and simulating depth in 2D images. It covers methods such as convergence, collusion, shadows, atmosphere, and depth of field using tools like Firestorm Phototools. The document concludes with an exercise for readers to practice creating depth in their own images and submit them for feedback.
