redscale film

redscale super 8 cartidges good idea?

[BAC]

Are you talking about re-spooling a cartridge? I think it would be a lot easier to experiment with it using regular 8 film.

[longlivefilm]

please forgive me for long delay in replying what i ment was why cant kodak sell redscale super 8 cartridges if they cant maybe pro8mm or spectra or someone in europe should?

[Andreas Wideroe]

What's redscale film anyway?

[S8 Booster]

Should require Kaccemas or new Kodak cart buidls. (empty new)
Wittner sells empty Kodak carts iirc.

redscale film is color film the wrong way round the light enters the film the with the dye layers in the wrong order this can produce freaky striking or bizarre color an example is on vimeo just search redscale , a guy has uploaded a 16mm fuji film in redscale but fuji has a remjet backing and when the film is exposed the remjet acts like an n.d. filter of a very high filter factor causing the footage to look like day for night but with the redscale effect, if he had used 16mm ektachrome that does not have a remjet backing the underexposure would be much reduced.

I think this is the clip you are talking about: http://vimeo.com/9668610

The redscale effect would not really work with ektachrome because its reversal film so it does not have the orange cast of colour negative which is what causes the redscale effect. AFAIK all colour neg. motion picture film has remjet on it.

Although the redscale effect is pretty cool looking I think you'd get a similar effect in Super 8 by simply putting a coloured filter on your lens. You could also buy coloured gels or stained glass and put those in front of your projector lens fora tininting effect.

indeed it does work with ektachrome. it isn't the orange colour bias that causes the red effect. Rather it is a product of the colour emulsions being in the reverse order - red first, then green then blue. The red emulsion (which is usually on the bottom) is exposed to the most light when you have the film loaded the red-scale way. Also, the yellow filter, which is between the blue and green emulsions, is now before the blue emulsion, thus preventing any blue light from getting through to the blue emulsion (some blue information will be recorded on the red and green layers, but will activate red and green dye, not blue).
I have had a few customers load standard 8 ektachrome accidently the wrong way and get the red scale effect.

OK Richard, thanks for the detailed explanation of the effect! Do you need to overexpose it to get a good image? The poster of the Fuji redscale 16mm suggested 4 stops over.

[richard p. t.]

The results that happen by accident in standard 8 mm that I have had come through our lab are always a bit under exposed. I wouldn't have thought 4 stops. As always, its down to testing. But yes, I believe to get the best results you should under-rate the film.

Here's a frame grab of some accidental redscale footage shot (anamorphically) on double 8 Ektachrome:

Definitely under-exposed, but there's still quite a bit of information retained. Gives some very eerie landscapes. I graded it back to B&W easily enough, though it's pretty grainy. I'd probably go 2 stops over if it was intentional.

Looks red.

Always fun to experiment but I don't see the appeal.
