Visual Effect

Visual Effects are the process when the imagery is created. Visual Effects are a mixture of live-action footage and computer generated imagery and this is to create the environment to look close of reality, but this could be very expensive and is impossible to catch it on films, it needs the help of a computer. Also it could create simple things that are visual effects, as we as class did.

There are some visual effects that are divided in four categories:
* Models: Small sets, models and animatronics.
* Matte Paintng: These we are studying right know. Digital or traditional paintings or photographs which are useful as backgrounds.
* Live-action effects: Keying actors or models through blue screening and green screening.
* Digital animation:Modeling, computer graphics lighting, tecturing, rigging, animating, and rendering computer-generated 3D characters, particle effects, digital sets, backgrounds.

The Visual Effects are often used during Post-Production, here is when the computer and the shoots are working together to get the Final Product. In the Post Production the films are edited with the graphic designs, animation and similar software. Also there the editors use special effects that are made on sets.
