Digital Effects in the Movies
Myriad sites explain how Computer Generated Imagery (CGI) is used to create special effects, alien environments, and even entirely new creatures in modern cinema.
Digital Synopsis has a good overview of numerous films before and after special
effects have been applied. It's a great way to see the basic setup of green screen, texture mapping, and other relevant technologies.
Industrial Light and Magic (ILM) have been pioneers of visual effects for decades. In addition to this digital effects breakdown
of Star Wars Episode VII - The Force Awakens, their
YouTube channel has videos for many of their films, including Kong: Skull Island, Deepwater Horizon, and
Warcraft. The ILM website is another must-visit.
Pixar are also leaders in this field, and their
web site houses excellent resources that shouldn't be missed. How Stuff Works covers ILM's The Perfect Storm,
while Popular Mechanics covers Transformers.
Lord of the Rings: Digital Horses and Black Swan Effects
Reel are two behind-the-scenes style videos. And, of course, no discussion of film special effects would be complete without an article
about the special effects in Avatar (BBC).
