Why is a scene shot with green screen for adding special effects?

You might have seen in the behind the scenes pictures of numerous films and shows that the unrealistic scenes or dummy are shot with green coloured backgrounds. Have you ever wondered why the background is green and not any other colour such as red, pink, purple or white?

Green is the go-to colour because it is indifferent to nature. It doesn’t match any hair colour, natural skin colour or body part making it easier to edit. In this way, no part of the human body is edited out in the chroma key. However, if a green costume or prop is required the green screen is replaced with a blue screen.

The colour green is pretty odd and stands out. So if the actor is wearing a pink dress in front of a pink background then the chroma key while replacing the background with an image would pick the dress’ colour to replace as well. Green screens are also more commonly used because of the colour green being the highest luminance among all the colour channels (RGB).

Nowadays blue screen is used in place of green screens because blue is a much softer colour. They are easier for chroma-key too.

The shooting of blue screens and green screens differ on the basis of what is in front of the screen. You cannot shoot a green parrot in front of the green screen and similarly, you cannot shoot the blue avatar characters in front of blue screens. Like when they shot Green Lantern or Hulk they definitely used blue screens. It is always good to have options in handy. Use of chroma key is taught to you in visual effects courses.

In post-production studio, VFX artists use chroma-key to edit the screens and replace them with required background and images. The dragons on Game of Thrones are nothing but props with green coloured wraps. They later appear on the screen as dragons carrying the Queen of seven kingdoms.

Now that you know the real reason behind adding the green/blue screens for special effects it is no more confusing why other coloured backdrops are not added.



Oscar nominated movies for their highly creative VFX

vfx, vfx training

The Academy Awards nominations for 2018 are out and we cannot wait to see which film carries the Golden statue for best VFX. 2017 was the year of stunning visually aesthetic films. We saw some great performances with high-quality visual effects.

Although, it appears there is possible no competition to Blade Runner 2049. Visual effects artists John Nelson, Paul Lambert, Richard R. Hoover, and Gerd Nefzer are nominated for this particular film. They pulled off the most difficult thing in the history of cinema. CGI can add false backgrounds and create supernatural elements but this time they brought back a whole another character to life. Rachel in Blade Runner 2049 was a CGI recreated element altogether.

It appeared as if she hasn’t aged a day since 1982. And technically speaking the CGI version was a replica of her from 1982 only. The other films nominated for this year’s Oscars are Guardians of the Galaxy Vol. 2, Kong: Skull Island, Star Wars: The Last Jedi and War for the planet of the Apes.

The history of Kong’s CGI has been through all kinds of stages; right from using traditional means of computer graphics to moving forward to modelling it over the computer the Kong franchise has seen all kinds of transformations. Same goes for Star Wars: Last Jedi. The first Star Wars movie ever directed was filled with CGI fallacies but this film was a whole package of stunning art. This is that time of the year again when people start hunting for animation and VFX courses after watching these great performances.

If you talk about War for the Planet of the Apes, the film was literally shot in front of green screens and with people pretending to be apes. Actors often joke about how these days they do not need plastic surgery because visual effects do the trick for them. All these films nominated for Oscars have one thing in common; that is a bunch of people who are driven towards one goal of creating fantastic cinema.
