Professional camera shooting special effects

The space sci-fi blockbuster "Star Trek: Darkness Boundless" rarely shoots scenes with IMAX cameras for more than 30 minutes. It is the first version of IMAX3D in sci-fi movies, and it has also been warmly expected by more than 90% sci-fi fans.

As an important part of film art, film stunts provide strong technical support, aiming at creating a unique visual feast for the audience and giving them a real "immersive" feeling.

Hollywood blockbusters use a lot of post-production techniques, especially digital special effects, which create the real world in film and television art, but also create unusual "dream world" and "superman" stories.

Some sci-fi films, disaster films and action films with high difficulty and big investment have widely used digital special effects, which has changed "virtual reality" and "future world".

So, how are these movie special effects used?

Models of people, monsters, buildings and vehicles are all used to make movie special effects.

When models must be moved, we can move them in any of the following three ways: by hand, by machinery or by electricity. It takes a long time to move them by hand, because the model needs to move at least 24 times a second on the screen.

Filmmakers use them to avoid putting actors in danger, reducing the production cost of movies, or just to make movies more exciting. In film and television shooting, people, monsters, buildings and other miniature models are often used to meet the needs of film special effects.

With the development of computer graphics computing technology, the production speed and quality of film special effects have made great progress, and producers can complete more delicate, real and shocking picture effects on the computer.

For example, Maya software can be used to produce effects that cannot be achieved by actual shooting or props, such as wind, rain, lightning, landslides, ghosts, aliens, house collapse, volcanic eruption, tsunami and so on. Moreover, Maya software can also be used to make simulated characters, such as the mouse in Elf Mouse Gori, the squirrel in Ice Age, Master Yoda in Star Wars and so on.

In film and television, people create illusions and illusions through computer technology, which are called film and television special effects.

Special effects can be divided into two parts, one is stereoscopic effects, and the other is post-effects. Both of them are very important in the field of special effects, and they are indispensable and complement each other.

Three-dimensional special effects are easy to understand, that is, making three-dimensional related content through three-dimensional software technology.

Post-special effects refer to the synthesis of real shot content, photo material and 3D software rendering material to get the final effect.

These two parts complement each other, and being familiar with post-special effects can help producers provide more ideas and solutions in the process of 3D production. Some effects can be done in three dimensions or later, while others can only be done later. If the producer is proficient in the application of post-special effects and three-dimensional special effects, he can choose the best production scheme with high efficiency and pursue the best quality.

Keying, which belongs to the late special effects part, is to excavate the material and remove the redundant parts in the real shot material. For example, when watching movies, we often see spectacular scenes. There is a man standing on the mountain, and a volcano erupts in the distance, and the flames are soaring. In fact, this kind of scenery is generally not found when shooting, and it needs post-processing.

We often see in movie tidbits that actors stand in front of blue or green cloth to shoot, which makes the foreground characters and background have color difference. The producer cuts out the blue or green shooting area, and then combines the special effects scene with the shooting character through cg animation technology to get the real shocking effect.
