Here are a few shots I worked on during The Conspirator:
Created mattes of the crowd and set pieces via rotoscoping and distributed them in Z space so that more green-screened people could be added. Also, painted out none-era appropriate objects, such as security cameras.
Created mattes of the crowd via rotoscoping to add additional people into the scene.
Modeled and textured the flag pole. Also rotoscoped some of the people/animals in the background.
