From the direction of the swirl you can work out whether you are in the northern or southern hemisphere.
Very handy when you set your satnav to take you to Euston and it starts directing you to Euston in Australia

 

I learnt that Technicolor used Eastmancolor negatives to shoot in one strip as from the year 1954. Did you know that?

I had learnt that Eastmancolor (Kodak) invented one strip color process but I thought Technicolor learnt from Kodak and used it on its own. The fact was not even that. Technicolor used Eastmancolor (Kodak) negatives to shoot in one strip. Technicolor lived of Eastmancolor as from the year 1954. What a shame for a company as big as Technicolor.

Till the early 50s, Technicolor was the only color brand in the entire USA. It was big but it became small living of another brand as from the year 1954.

The only thing that belonged to it became its dye transfer as from 1954. That was its difference from Eastmancolor.

 

So I think I know some things now

 

I like a little bit of O3, to kill the pathogenic bacteria and give the viruses a headache.

 

Meanwhile the public question the science!

 

It's still trying to understand Technicolor. It came up a lot while I was reading wikipedias to movies.

 

Technicolor is an american company founded in 1915 to make color films. It started in 1916 with earliest version of 2 strip process (there are 3 versions of it), then turned into 3 strip process in 1930s. Technicolor was the only color company in the entire USA until early 50s...So it was so big. It had all the USA till early 50s.

 

It is a very complex subject. One that requires a full understanding of the entire colour process from filming, to editing, to the production of internegatives. It would take hours to explain. You would also need a knowledge of additive and subtractive colour. RGB and YCM.
Dye transfer was only used to mass produce cinema film PRINTS. The setup cost was enormous, but it then printed on filmstock with no photosensitive layer. It was the same as printing on paper using lithography.

 

That's more complicated than I thought.

 

Complicated

Most people do not realize that Technicolor is a process, it is not a film. The filmstock used was originally Eastman-Kodak (Rochester NY) production. The process was fine tuned to allow European stock (French) to match, along with Agfa and Fuji. It all became even more complex when Agfa negative soundtracks leapt ahead and applicators had to redevelope the soundtrack the soundtrack area of cinema films during processing.
Grandy has asked me about this, but it would take hours, if not days to fully explain.
