Both the K40 and 64T data sheets call for filtering in daylight. It seems to me that both films are moderately slow, so I am rather puzzled (especially with K40).

Could someone please clarify this?

Thanks.

Both are tungsten balanced, so require filtration in daylight- 80A for K40 and 80B for 64T (the T stands for tungsten).

Nope.

It's 85s.
The 80s are blue for correcting tunsten light for daylight film.
The 85s aer orange, to cut the blue of daylight.

Okay, so what would you recommend for 100D?

I purchased what is called "Cine Chrome 100D". It is a 25 ft. double 8 reel for my Bolex P4. Unfortunately, I have no idea who manufactures it.

I think this is Kodak Ektachrome 100D which was specially ordered from Kodak by some German outfit. Knowing Kodak the minimum order is probably 312,000 feet unless they were able to negotiate a smaller order somehow. If anyone knows how, I would be curious to hear about it.

On the other hand it could be made by someone else. A number of companies have made 100 ASA color reversal films. Some not very good.
