I was one of the last people at Disney to use the Sodium Vapor light system. It was on "Something Wicked This Way Comes" in 1982 or 3. I was an vfx AC at the studio. The prisim was held under license from Rank. It was a hallowed object. It was kept in a steel box and it was studio policy that 2 AC's had to be with it at all times when it was removed from the storage locker. We both carried it to the stage, then carefully inserted it into the 2-strip camera. It was never left alone on stage, we took turns leaving for lunch, the john, etc. It hadn't been used for years but we had a series of tough matte jobs to shoot so they dusted off the old gear. I was aware I was watching a bit of history. The key was the didymium filter in the prism. That thing has to be around somewhere. Technically, Rank would still own it.

FYI, your sodium lamps should be upsidedown or sideways for longevity. If you have the electrodes on the bottom they'll get dripped on by sodium which will eventually cause the bulb to fail. If used properly LPS bulbs will last pretty much forever. This is a very clever technique. Well done

This is actually incredible and extremely useful, specially for low and mid-budget film productions. This technique severely cuts the amount of work hours necessary in editing, while also giving higher quality results. This can drastically improve the quality of videos and movies at a relatively low cost. Massive props to everyone involved in this project.

@Th1sUsernameIsNotTaken 25 дней назад

It'd be worth it in high budget too. They could utilize the effort of having to change 400 different settings constantly to make it "perfect" into other portions of the film. CGI would probably be drastically improved in film compared to what it is now.

The only giant limitation I would say is when it comes to shooting outdoors. Earlier in the video, they needed to block the skylight. Like, filming with natural light is already a pain (trust me I’ve been there).

In the front-screen projection that was used on 2001 and, also Aliens because Cameron is James Cameron, there was a special 3M reflective material that was necessary for the projection surface. Did the original sodium process use a special reflective backdrop, or was it basically just a cyclorama?

For those interested in the original (and often uncredited) people behind the process: Vic Margutti was a key participant in Rank Films travelling matte work- possibly with or under Bryan Langley. Vic left Rank to form a sometimes volatile creative partnership with Les Bowie as Bowie-Margutti Films. In 1956 Margutti was lured back to Pinewood UK to develop the new sodium vapour matte process - which proved very successful and would be adopted Stateside by Ub lwerks and Eustace Lycette at the Disney corporation as their travelling matte methodology of choice for decades.

@biffmercury Месяц назад

I read that when presented with the script to THE 3 WORLDS OF GULLIVER (1960), Ray Harryhausen insisted on doing it in England, where he could get access to the sodium vapor process. Even then, Harryhausen didn’t want to fool with the often unreliable blue screen process. He used the process on GULLIVER, THE MYSTERIOUS ISLAND (1961), and JASON AND THE ARGONAUTS (1963). Apparently it was no longer available to him for THE FIRST MEN IN THE MOON (1964), which utilized blue screen. Oddly, the technique was used on Herman Cohen’s KONGA (1961), and about the only impressive thing about that movie (and apparently the VFX person responsible for it, wasn’t credited on it, perhaps by choice). I wonder if it was used on THE CRAWLING EYE (1958).

A hardware solution needs to be made one at a time, and unless they acquire one for themselves, is probably stuck with the film company.

If I understand correctly (which is a big if), the original method uses all of the light and just redirects the sodium line.

I’m sure there was a lot that needed to be fabricated. If the two digital cameras aren’t perfectly in sync, the footage would never line up.

That being said, I think that they proved that the technique is feasible with modern technology and digital cameras. It sounds like they originally did this with existing synchronized film camera technology. I think one of the key advantages of modern chroma key is that everything is done with a single camera.
