Today's film industry has at its disposal technical innovations that few imagined decades ago. Despite this, directors have always taken advantage of the technical resources at their disposal to capture their stories, visions and imagined worlds.
In fact, special effects or visual tricks have existed since the creation of cinema. Its magnificent evolution has accustomed us to films in which retouching, in production or post-production, is key and increasingly imperceptible. However, would you know how to distinguish between FX, VFX or CGI?

Differences between FX, VFX and CGI
It is important to start by differentiating the most common terms or categories in this field:
FX or SFX are, if we translate it directly, simple special effects. That is: a visual trick, optical illusion or mechanical effect that is performed during the shooting or production of the film.
VFX is the stylized abbreviation for visual effects: visual effects. In this case, it is work that takes place from 3D or in post-production from digital technology.And what is that technique? Computer-generated imagery or CGI (computer-generated imagery).
CGI, thanks to the current technological power, has become a great ally for audiovisual creators, since it provides visual content that would otherwise be irreproducible, very expensive or not credible. In short: it makes the artist's imagination real.
There are other technical terms that are similar but do not indicate the same thing. For example, CG is not the same as CGI, but refers to the creation process and/or the data that will generate the CGI. Likewise, "3D animation" is generally used to describe the process by which characters and environments are brought to life and their outcome as an audiovisual project.
Some milestones in FX, VFX and CGI
Back to the beginning: special effects have always been used. Every era has had iconic films whose FX, VFX or use of CGI has impacted viewers because it has taken them to places or recreated characters they couldn't believe were right in front of their eyes.
