outdoor filters

Hey all, I'm going to shoot my first rolls of color next week and need some advice. I am using Kodak 7240 (yes, 16mm) outdoors. The film calls for a #85 filter. I purchased a 85B online (thinking I just got an 85)...my question is, send it back, or will it work?

Thanks everyone!

Sam

The 85B is what you want for the Ekatchrome 7240.

Good Luck

ok, getting annoyed, having to login for every reply!

Thanks for the quick answer. What really is the difference between the 85 and 85B? I'm assuming the B is Blue...haven't opened it yet and don't really want to until I'm ready to shoot.

What will the effect be?

Thanks again

The B is 200k warmer than the 85.

Good Luck

85B decreases the color temperature from 5500K to 3200K, and 85 down to 3400K. Former is for 3200K balanced film. Latter is for 3400K balanced flm. If you use an 85 filter with a 3200K balanced film you get a slightly cooler (bluish) result.

I shot my first "Monster" movie with Regular 8mm 7240 with the 85 filter, the blue tint really helped in the low light outdoor shots, it gives a funky "real" feel I think.

Cheers,

The ASA of 7240 with the 85b is reduced to 80. What would the effective ASA be reduced to with the cameras built-in 85(90-100?)
Thanks.

Kodak Spec for the 7240 actually no mention of the 85B filter but here is the full spec avail from them.

I have shot the VNF 7240 with both the 85 & 85B and I saw no real noticeable difference between the two.

The box of super8 actually states the 85b. if the color temp is different by 200k there will be a difference in ASA that is faster than 80 ASA .

huh? What speed will I be running then? 80? I only need to know so I can plug it into my digital lightmeter.

thanks

With the 85 filter, again I agree with the above mentioned. You will get a blue tint to it since it is cooler by 200K if it was warmer you'd notice.

The 85b filter is the one suggested by Kodak because it will be the closest mark to natural color reproduction. Its how all their films are rated (I assume) by their color reproduction.

I remember that all the ads I have seen for the old K-11 Kodachrome and Kodachrome II all note that they reproduce colors with "startling realism".

So, what you film is always suppose to be reproduced closest to the real colors that were present, filters and all.

(Could you warm the 85'd film with a Skylight filter?)

Yes, outdoors with the 85b filter you will run an ASA of 80, I think with the 85 you might have an ASA of 100.
