Filters?

[miguelito]

What is the difference between an 85 filter
and an 85B filter? I have a roll of super-8
Vision 200T neg. film. On the box it says to
use an 85 filter. Can I use it in a consumer super-8 camera with a built-in filter?

Yes, they are talking about the 85b filter that you have in the camera already.
There are other 85 filters, like an 85a,but for this situation it doesn't really matter.

That filter is only good for daylight, otherwise tungsten light needs no filter with 200t since it is already ballanced for tungsten lights like most other S8 film.

I just found a list for anyone that cares.
85a compensates type A film (3400*K) for Daylight use.
85b compensates type B film (3200*K) for daylight use.
Without these, the image will be exessively bluish, more so with type B film which seems to be all the film I have in my fridge right now.
If one forgets to use the filter out side, could one put a filter in front of the projector to ballance it?

THE FILTER IN YOUR CAMERA IS AN 85A!!!!

KODACHROME IS AN A RATED FILM.

Neg stock is rated for an "A" filter. The differance is that an "A" filter takes the film to 200 degrees more on the "orange" side of Kelvin.

This why when you shoot the 7240 with an "A" filter it looks blue.

Good Luck

Thanks 8th Man.
As for your question about using a filter in front of the projector lens: I guess it would work but I suspect it would cut-down on the intensity of the light.

Thanks for the clarification Nigel. K40 is an "A" film so the in camera filter must be an 85A, I don't have an in camera filter on my Beaulieu and I don't shoot K 40 much but now I know I'll need an 85A for that.
Are you sure Neg. is "A" film too? All the Neg. I have says 3200* and according to my filter chart that means "B" film and requires an 85b.
Is this right? Does it really make a big difference?
