Claire Wan asserts that when you watch a movie, you’re bound to get goosebumps. Many scenes are eerie, frightening, or just plain cool. It’s expensive to capture these situations in real life, so visual effects are used to make them look as real as possible. Whether the scene is a monster fighting zombies or a gruesome crime, the visual effects in movies must be realistic enough to make the audience feel as if they’re watching the scene themselves.


Filmmakers use lighting effects to enhance the visual quality of their films. There are three major types of lighting effects used in movies. The key light, the fill light, and the hard lighting are used to balance shadows and highlights. Key lighting emphasizes the actor or actress being filmed. Fill light cancels shadows while hard lighting creates deep shadows. Each type of lighting effect is vital to the final result. In addition to key lighting, filmmakers use special effects lighting to enhance the effects of the film.

In addition to creating a mood in a film, lighting can evoke different types of emotions. Typically, lighting in dramas focuses on one main character. In other movies, the lights may move along with the characters. In such situations, a dolly track is used to move the lights from one location to another. Lighting enhances camera angles. By creating the appropriate mood for a scene, a director can achieve the desired effect.

Rendering by Claire Wan

The production of high-quality, life-like images is a key component of CGI films, and renderers are critical to the success of such projects. This process involves turning 3D models into 2D images and can take days, weeks, or even years to complete on a single computer. Fortunately, today’s more advanced workstations and render farms can handle higher-quality rendering with significantly less time, cost, and effort.

To produce high-quality, lifelike images, film makers use computers called render farms. These large, high-powered machines combine various elements in order to create realistic scenes. While a single home computer is unlikely to be capable of producing such realistic-looking images, a large animation company may require thousands of render machines. The amount of computing power needed is huge – a rendering farm can be as powerful as four million desktops.


There are different types of compositing, and many smaller aspects of the process. Compositing is one of the most important aspects of this process, as it combines separate visual elements into a single image that gives the appearance of being part of the same scene. Some compositing techniques involve using green screens or chroma keys to capture live action shots. If you want to make realistic 3D scenes, you might want to think about compositing as a career.

Match-moving by Claire Wan

The most important of visual effect  thing to note while creating a match-moving VFX is to have a lot of information. While many of the techniques for VFX are similar, match-moving is unique to this technique. To create an accurate match-moving VFX, an artist must have precise information to create a realistic scene.

The tracking method relies on software that will generate tracking points, which are reference points that follow the actor’s movement. The match-moving software then uses these tracking points to create a 3D environment. These markers are important because they help the match-moving software accurately reconstruct a scene from incidental footage. The match-moving process is interactive, so it is crucial to have accurate tracking information.


Many people may not realize that visual effects are a huge part of the filmmaking process. While many visual effects shots aren’t overly impressive, they enable productions to shoot in other locations or solve set problems. Those effects are the reason that trailers and other marketing material include these special effects. But what exactly does it mean to use visual effects? How does it benefit the audience? Let’s take a look at some examples of visual effects.

Many films today incorporate visual effects to enhance the story. Computer graphics (CGI) is one example of a type of VFX. Other forms of visual effects, like double exposure and motion capture, use computers to augment live action. In the filmmaking industry, visual effects are the backbone of storytelling, and they deserve their own special Oscar category. As technology improves, so do the tools used to create them.
