Today, Bian Xiao watched a movie "Ant Man" adapted from classic superhero comics. Although he missed the film when it was released, Bian Xiao was shocked after watching it again today. I really admire director peyton reed! How did he make Ant Man smaller? How is the shooting effect of the micro-world achieved? What special effects techniques are used in the movie to make it so realistic? This makes Bian Xiao curious, if you want to know the mystery! Then let's take a look with Bian Xiao!

The director's idea is beyond your imagination.

Ant Man wants to create an excellent micro-world for the audience in this era. Director peyton reed revealed in an interview: The idea of this film is to make the miniature world look different from the world in front of us, and at the same time, it is realistic. According to past experience, it will be found that when I was young, it was an adventure film, and when I was older, it became a disaster film. Director peyton reed used macro photography and macro camera technology, coupled with motion capture technology, miniature photography technology and CGI and other special effects, successfully brought the audience into a familiar but unfamiliar micro-world. Compared with the explosion, flight and battle scenes, these parts in the film are more amazing, especially a series of scenes after Scott Edward Harris Lang was first scaled down, which are impressive.

From the perspective of Ant Man, the world is full of amazing details, most of which are hard to see at ordinary times. This demand for details ultimately promoted the creation of macro scenes in Ant Man's eyes. Through a series of technical efforts, the film achieved the best visual effect. For Ant Man, the biggest challenge in the film is undoubtedly how to deal with the three-dimensional effect of Ant Man when it is minimized.

Director peyton reed explained that we used many techniques to create zoom effects, including macro photography of moving images, macro photography of fixed images and motion capture. We will put Paul Rudd and stuntmen in special costumes and make videos with digital technology. No matter what kind of panoramic shooting scenes we have, there will be corresponding miniature scenes. We will shoot with some special lenses, and then remake it, because you have to restore all the textures, so that it can feel real.

Macro photography, scare away Bian Xiao!

Many scenes in the movie Ant Man were shot at macro. Macro photography refers to the process of shooting tiny objects or tiny parts of objects at close range within ten centimeters. The magnification m of images and objects is usually defined as 0. 1 ~ 1, and some literatures even extend it to 10. Magnification, also known as copy ratio, is the ratio of image size (referring to the image size on film or image sensor) to the actual size of the subject. Macro photography is similar to looking at things with a magnifying glass. Some small objects will make you see clearly, and some details that you can't see clearly will suddenly appear. It can be recorded, so its primary application is reflected in science and technology. By observing and analyzing the clear panorama of small objects through photos or images, this technology has a wide range of applications, including: medicine, archaeology, physiological anatomy, textiles and so on. It can shoot scenes that people can't see or see, so that researchers can observe and analyze them carefully.

Motion capture, it was so funny when shooting.

Motion capture is to capture the actions and even expressions of performers, and use these actions or expressions to directly drive animations and virtual object models to produce vivid animations.

With the help of computer technology, motion capture technology captures the movements of key points of an actor's body and face by means of measurement, tracking and calculation, and then integrates them into the constructed computer three-dimensional model, so that the computer three-dimensional model can make actions similar to those of an actor. For example, stick flash balls on an actor's hands, legs, face and other key parts, let the actor do the action of fighting with the tiger, and use special instruments to capture the trajectories of those flash balls, and then give these trajectories to the same parts of the "actor fighting with the tiger" that have been generated in the computer. In this way, the "tiger killer" in the computer can also make the same actions as the actors in reality. Paul rudd, the star of "Ant Man", admitted in an interview that this was the first time he shot with motion capture technology. He said that in front of the green screen, pretend to feed ants or ride ants, or avoid someone's feet. You just have to pretend. Fortunately, you know that people who are very good at doing this kind of special effects will deal with it later, so you will feel a little excited, "Hey, I am here to feed ants or ride ants", and you will know what this scene looks like in a few months.

CGI technology, this must be there.

CGI(Computer Graphic Image), also known as 3D animation, is a computer image technology widely used in movies, television, electronic games, interactive multimedia and other fields. It is a new technology in recent years, and more and more movies adopt this technology. The film Avatar directed by James Cameron 20 12 has 60% content and nearly 3000 shots made by CGI. This film realizes the perfect combination of CGI technology and computer special effects, and brings a visual feast to the audience.

As early as 1970s, CGI technology has been applied to movies and has become an important means in film production, beginning with the "Yoda Master", "Jabba" and various aliens created by Hollywood visual film artist george lucas in his Star Wars series.

Corey stoll (such as Darren Cross in Ant Man) mentioned in an interview that the original "Ant Man" armor was very retro and real, while my armor was completely computer-generated. But the implication behind this is that the technology of making this kind of armor is so out of this era that you can't do it at all. It must be expressed by CGI. It's a pity that I really can't wear this armor, but considering the reality of shooting, it's quite comfortable.

After watching Ant Man, we can't help admiring Ant Man's ability to shorten and lengthen, and the illusion can also save the world with Ant Man's uniform. So, if you were really asked to make a similar movie one day, what skills would you use?
