Hello ,
I am filming a S16mm short called Red Hood.

We are getting the rushes from technicolor UK on digibeta.

The director would like to desaturate the colors completely leaving a B/W image but he wants lo leave the reds on. This is called Red Hood, and it?s the fairy tale story used as a canvas for this project. Since there won't be really a budget for a DI, I was hoping to get as close as possible to this idea in a TK grade, mastering hopefully to HD mainly because I was trying to avoid any tape to tape grade if possible although now I'm thinking this may be a job for a Flame, Smoke, Inferno, Combustion, Shake or similar. Perhaps grading normally and do all the color desaturations later on. We won't be scanning back film.

I would appreciate any other suggestions you may have.

Thanks

Read about R. Rodriguez and Sin City. It's somewhere out on the net, they did exactly that, for Yellow and Red.

Mokey/Monet http://www.mokey.com/products/monet/

But they Shot Sin City against a green screen/chroma.

Why do you need a tracker?

You'll need to mask off a alpha for the areas that remain in color (red in your case). De-saturating the rest.


After Monet, you can move to say... Shake or After Effects for compositing.

A good colorist with a DaVinci 2K+ or Pogle platinum should be able to isolate the color you want and desaturate the rest without having to resort to tracking. Even if they do you can draw a shape in the CC and do an inside-outside correction he may need to setup a garbage matte or similar but the newer Colorist tools will certainly allow for this and are quite commonly used for commercial (spots) finishing.
