A deep dive into VFX History looking at colour film and colour matting / color matting.
When I made my video exploring Optical Printers and how they could be used to remove blue from a scene, I was left wondering how did film know which colour was which? And if someone is wearing blue, like Christopher Reeve as Superman (1978) how was he able to be keyed into flying shots. And then I started to question how live analogue TV was able to "remove the blue" for weather forecasts and original Doctor Who.
Join me down the rabbit hole of colour film (or color film) Technicolor, Eastman Kodak's Kodachrome and Eastman Color. We'll take a diversion to look at colour analogue telly and CSO (colour separation overlay). Once we're back on track, we'll learn about Petro Vlahos, Didymiun prisms and the Sodium Vapour process. And then, we'll take a diversion to look at how Star Trek: The Next Generation developed the use of UV light and flourscent orange screens before we finally crack the puzzle that made us beleive a man can fly.
I also have to give a MASSIVE thank you to both Star Trek: TNG's Visual Effects Supervisor Dan Curry (who helped me with a load of research) and VFX artist @RustyGellerSteadicam for his interview and insights.
Check out Rusty's series, What's Behind the Eye behind the camera: youtube.com/watch?v=vR046LZ_NU4&list=PLmVlIQ0mLCqbTGLR67OW1BwXSAQAId7_C
I've tried to sum up my findings here and inevitably, I will have missed out crucial steps and glossed over important points. Still I hope you find this VFX history entertaining, if not informative.
If you're wondering what software I used to create all the animations, I used Adobe After Effects and Video Copilot's Element3D. Blender was used for a couple of the models. If you have any questions about any specific parts, drop me a line in the comments.

![Recreating Doug Trumbull’s Slitscan VFX | After Effects Mastery
In this After Effects tutorial, Im diving into the legendary slitscan effect. While Doug Trumbull used a massive mechnical righ and long-exposure photography to create the Ultimate Trip, Ill show you how to build the same look much more easily using *Essential Graphics*, the *Offset effect* and *3D layers*.
In this video, youll learn:
- How to use the Offset effect with a simple expression for continuous motion.
- How to use Essential Graphics to control the speed and images
- 3D layers to create two infinite plains.

![How to get Uniform Scale Wiggle in After Effects
An Expressions tutorial.
The wiggle expression is a great way to introduce randomness to your image, solid or shape in After Effects, but when applied to scale it wobbles both dimensions separately. What happens if you want to wiggle them both together?
Dont worry, its a simple solution and just requires a little bit of understanding about how the Wiggle Expression works.

![Recreating the Genesis Effect from Star Trek II: the Wrath of Khan
An Adobe After Effects tutorial
KHAAAAAAAAAN!
In this video, I look at how to recreate the iconic Genesis Effect as simulated by some of the very first CGI in movies. Star Trek II : The Wrath of Khan (1982) used a Cray supercomputer to render the minute long sequence. The shot was reused in both Star Trek III : The Search for Spock and Star Trek IV : The Voyage Home, so you know it must have been good. In the sequence, a torpedo is fired into dead moon, which is quickly covered in fiery particles. Then the surface glow fades to see greenery and water appear on the surface before pulling back to reveal an M-class world with clouds.
It’s an awesome sequence and the hardest part turned out to be the camera move, which I had to give up on, still I think I capture the feeling of it. The tutorial only uses the included effects and one plug-in, the free Orb effect from @VideoCopilot. It’s a long tutorial and I have focussed more on the techniques involved rather than trying to match everything exactly.
