9 Visual Effects (VFX) & various Visual Special Effects Techniques
Visual effect (VFX) is the integration of live action and a generated environment to create realistic effects. Currently, Computer-Generated Imagery (CGI) is the most widely used technique by most of the filmmakers.
Here are some of the techniques that are being used in VFX.
1: Computer-Generated Imagery
Computer-Generated Imagery (CGI) is the most widely used technique deployed to generate computer graphic images, which can be used in print media, films, art, videos, television programs, and more.
2: Bullet Time
Bullet Time is a visual effect technique that detaches the space and time of a camera from the visible subject. It can be seen in broadcast advertisements, films, graphics in video games, etc.
It is technically known as time-slicing, virtual cinematography, and view morphing.
3: Virtual Cinematography
Virtual Cinematography includes a variety of subjects (like real objects), multi-camera setups, etc. to create 3D-objects.
4: Digital Compositing
Digital Compositing involves assembling of multiple images to create a final image, screen display, or movie.
This process is run using digital image manipulation.
5: Matte Painting
Matte Painting is a process of dying to represent a landscape or distant location. It creates the illusion of an environment that cannot be seen in the actual filming location.
Matte Painting involves manpower and physical effort by painters and technicians.
6: Motion Control Photography
Motion Control Photography is a VFX technique in motion photography that enables control and optional repetition of camera movements.
This involves filming various elements using the same camera motion and finally, combining these components into a single image.
7: Stop Motion Animation
Stop Motion Animation is a special effect where still objects appear to move on their own. This technique can include an object, models, humans, household appliances, etc.
The best example is the traditional flip book that involves sequential drawings on separate pages.
8: Prosthetic Makeup
Prosthetic Makeup is the VFX technique where cosmetic effects are applied to characters.
9: Chroma Key
Chroma Key is also known as blue or green screen effects, where two different videos are combined.
This is a new technique and can be mostly seen in movies in the form of travelling mattes and Schufftan process.
