When we watch movies we find many such actions, activities and scenes that make us surprise this is because they are not true and are completely illusion. These illusions used in the films, television and in the entertainment industry help in stimulating the events that are imagined in a story and presented traditionally called as special effects. in the high budget films the special effects are commonly used but affordable animation and compositing software enables even amateur filmmakers to create professional-looking effects.
The basic manner of presenting scenes with special effects is traditionally divided into several categories such as optical effects and mechanical effects. In the present scenario there has been made a great distinction between special effects and the visual effects and it refers to post-production and optical effects, and "special effects" referring to on-set mechanical effects. The optical effects are one way of bringing special effects in which images and film frames are created and manipulated for the film and video.
In a scene the optical effects are produced photographically which is done either through a camera, which involves uses of multiple exposure, mattes, or the Sch? process or through the post production process where the use of optical printer is highly utilized.
Mechanical effects are another method of bringing special effects which is usually accomplished with the live action shooting program. In the mechanical effects the use of mechanized props, scenery and scale models, and pyrotechnics are also used. The scenes where we see a car appear to drive by itself, or blowing up a building are examples of mechanical effects. Mechanical effects are often incorporated into set design and makeup. Like, a set to be involved in movie is often built with break-away doors or walls, or makeup can be used to make an actor look like a monster.
The special effects were started to be used since 1857 when Oscar Gustave Rejlander created the world's first "trick photograph" by including different regions of 32 other photographs into a single image. Again in 1895 Alfred Clark used special effect for the first time in a film. In the year 1896 French magician Georges M??discovered the same "stop trick." of special effect in his magic. By 1920s and 1930s the techniques of special effect were even more improved and refined by the motion picture industry these effects and techniques were modified presenting the illusion from theater. Soon several other techniques were also developed like the stop trick which was completely original to the motion pictures.
One developing form of special effects is the live special effects which are usually used in front of live audience usually during sporting events, concerts and corporate shows. Common types of special effects that are used in motion pictures and shows include a laser lighting display, co2 effects, pyrotechnics, flames and confetti.
