The development of the digital graphic system Computer Generated Imagery (CGI) becomes one of the most important elements in movie making. Although it may have its pros and cons, it did contribute a lot in many kinds of the digital media. Computer Generated Imagery use wildly on much different type of digital media, such as films, animation, video games, printed media. With this advance computer graphic, the special effects and 3D effect on those media can make the impossible thing become possible in the digital world. CGI can make our creative imagination come true so that to increase entertainment and visual enjoyment in the movie. Such as the superhorse movie, Superman, Spiderman, Batman, with the CGI, they become powerful, they can move cars, they can jump high, they can fly and they can have their super power. We can create any character we can imagine, such as monster, zombie, and giant est. Also, CGI can visualize anything that are abstract, difficult to present and hard to control in production a movie like animal and the nature power and effect, lighting, waving. In the movie Percy Jackson & the Olympians: The Lightning Thief, the main character can control lightning. Also, in X-Men series , all X-men have their special power such as they can control thundering, fire, ice, wind est. Also, in Harry Potter series, the Charters can use their magic is because of special effect of CGI.
As the development of the film industry, the variety of the film genre increased, CGI greatly apply in many film genre, such as fantasy, Sci-Fi, adventure, animation. In animation, the whole film is mad by CGI, even the background, or the characters. Each year we will have many kind of the animation coming to the cinema and the theme of animation are different, such as the most success animation, Toy Story series, Up, Wall-E. Those movies also got a lot of attention in the Academy Awards -Oscar. As the CGI and digital technology develop, now, 3D movie become more and more poplar, Avatar is the representative and it gained a lot of compliment.
Also, with the CGI, moive can become more realistic. CGI can increase the reality of the background, character, such war fighting screen, imagine world Such as the background scenes of Lord of the Rings and Alice in the wonderland. Moreover, the visual effect of the CGI can increase the reality and feeling of the Character, through the facial expression, digital make-up. In the series movie of Transformers, all robots are made by CGI (2011) and they are like the real, they just like transformed from car. In the recent movie Rise of the Planet of Apes 2011, it shows how the humanity Apes can be created from people actors by the CGI. CGI can surely enrich the movie, make the movie become more attractive.
For the cons of CGI, I think it is that filmmaker may over rely on this technology. They might rely to CGI to do all the special effect, character design, make up, decoration or even the role in the movie, they will all use computer to do it. In fact, it will affect the Character’s acting and performance, they will act without partner, he or she needs to act with no one, and that will be difficult to the character. Since using CGI become the trend on filmmaking, every movie tend to it, and even deal with small object like the basketball in sport movie, the balls, animals, or even background. Some poor production house, didn’t have the familiar skill to do the CGI, eventually, the CGI used in the movie are not real and unnatural. All these will affect the quality the movie.
CGI is a very awesome technology in filmmaking, it can even create a character from zero. However, I don’t think it can’t make actors obsolete. The real human can also make by CGI, but the real human emotion that induced from the heart can create by the computer. CGI just imitate the outlook of the human or other thing, but it can’t imitate the real emotion of the character. Even the emotion can be imitated, the audience may not feel touch by the character, because it is not real and not from the heat of the actor. However, some movie’s animation character are also rely on the real human actor to play, that means, the place of the actor is not replaceable.
For the animated characters, although them devoted a lot in the movie, but I still don’t think it can be nominated for acting awards competing with humans. Animated character relies on a lot of after effect and digital make up, decoration to build the image of the character. All the performance of them acting in the movie dependent on the new technology of the computer, so all things can be correct, amends. For the real human actor, it is all rely on their real performance and acting to lead the plot enriching the movie and attract the audience, let they more into the story. The emotion of the characters are real, it is from the heart., not like CGI. The performances of the real actor are more unique and realist. The actor work very hard to study and practice the skill of acting, talking, they may paid a lot of effort.
The disadvantage of Motion capture is that the cost of the software and hardware, equipment and the installation fee of that technology may be high. Also, it needs professional people to operate this technology, this will also increase the production cost. Also, there is not many equipments allow director to have real time viewing of the shoot, so problem will occur and many reshoot will be need. And there will be artifacts since the proportions of the actors or object and the computer model are not always the same and they may not fit to each other.
If we need to set up acting awards for the digital characters, I think we can separate the type of the acting awards, such as the digital characters are acted by the real actor and digital characters created by the CGI not acted by actors. Because I think human actors compare to digital animation character actors is not fair which human actors is acted by human with their hard work on acting skill, but digital animation actor is just created by computer programmed, it didn’t have the reality.
Motion capture is technique that recording the actors’ movement and later translate them to a digital model. This give advantages to movie making, especially on CGI and 3D technique. Motions capture help to record the actions of human actors, make creating the animate digital character become more convenient and faster. Also, this method capture the detail movement of the human actors, such as fingers , facial expression, so the performance of the digital animation characters will be come more realistic and nature. Compare to the traditional way of animation characters, the performance are also better. Also, the cost of making the keyframe in animation also reduced and the effectiveness is increased.

I think it is not the way that Animation should strive for photorealism. It is because they are totally two different things. For the film plot and the screen beauty, filmmaker will use the CGI to make the animation and make it look like the real object. But it is only for the aim to make a rational movie. However, photorealism is not the final aim for animation. It tends to create more creative and interest, meaningful story and use CGI to do the beautiful animation. Just like the DreamWorks Sky, Pixar, and Disney doing, every year they create new and creative animation for the world, and the movie always achieve the big success. Animation is seeking to do reality thing, the object, background and even the characters, they resemble the real things in the actual world. But it is for the aesthetic purpose, not because to seek for photorealism. Each animation have its meaning, value, they help remind us the simplest, naive and different kind of positive thinking. Personally, I love animation very much. I think it is a very unique movie type.
