outdoor filters

[S8 Booster]

The difference in colour balance with the 85 & B for the VNF7240 correctly exposed is marginal. If it gets a cooler look with the 85 at all - which is not my impression - it just looks pro footage - very nice.

I have also seen recommendations for shooting the VNF 7240 at ISO100/64 which is what I did when using the 85B filter (ISO100/64 not spesifically set to this for the 85B) and the result was very satisfying. ISO100/64 was no problem. I think it could have taken quite a bit more too.

I shot a 2nd VNF 7240 on a 514 xls which will (as most standard S8 cams) set the VNF7240 to ISO160/100 and normally use the built in 85 filter and allthough slightly underexposed those images came out really great too, Actually incredibly good colourwise so this film is kind of quite forgiving being a reversal. In S8 with its notching system it will very often be underexposed at ISO160/100 it can possibly get a slightly cooler look from the underexposure which of course may be corrected somewhat using an 85B but as said the results were still astonoushing with the 85/ISO160/100.

As I see it:
If you are shooting in R8/16+ and set the exposure correctly a 85 filter should be no problem at all.
If you shoot S8 when the film normally is auto set to underexposure at ISO160/100 you may in this case get slightly warmer results using a 85B.
That is probably the reason for Kodak´s S8 85B recommendations.

From an old post:
Exposure corrections listed below. Both the 85&85B drops 2/3 of a stop.

This seem to be a good one:

It's tough to filter for outdoors beyond doing guessing since colour temp can vary a couple thousand degrees. 5500 is an idealized bright sunny day. Shoot in overcast conditions and it can be 6500 or even more! Shoot during the "golden hour" and it's in the 3400 range. If you want to get exact, you'd have to use a color meter. I'm only guessing, but probably S8 Booster shot under the Nordic gray winter sky but maybe mixed with a low set sun -- giving him an close to ideal condition for a regular 85 over a 85b with 7240 or negating differences as conditions were rapidly changing.

Shot under various conditions. Off course daytime variations and light variation will matter. My results/impressions are turfed on the same base as Kodaks´: "These are start-off recommendations only - the rest is up to you to sort out."

Still, I am 99.99 % sure that the Kodak recommendations for the S8 85B filter use is because it gets quite underxposed; by far most cameras like 1 example; all Bauers and most Nizos + pobably all medium to lower end cams wil auto set it ISO160/100 vs 125/80 which may turn it somewhat bluish. Correctly exposed or slightly over this is not a factor as can be seen for the Kodak spec linked above. They do not mention the 85B at all for the 16/35mm VNF7240.

Various various lens coatings or lack of such will play a tune too of course.

So, in the end you will have to shoot a trial to verify your own gear and settings, according to Kodak and - me ;-).

I just did serval tests with a 7240 VNF loaded nizo 4056 with the built 85 in position in addition to my Gossen luna pro set at an ASA of 80(85 and 85b is the same ASA offset according to Tiffen, 2/3). Every test I did with a reflected light reading the difference between the cam and the meter is off by 3 stops.??? The camera been at f/4 and the meter at f/11. Both devices have fresh batteries and I know both work correctly.
Any reason why? And, which should I trust?
Thanks,
Ralphie.

This does not count for all but may be contributing factors:

Pretty sure your Nizo sets the VNF film speed to ISO160/100 not ISO125/80

Secondly the Nizos does not use "T" stops like most other cams so there is an additional loss to be addes. see list below.

Shutter speeds will also have to match ofcourse. Check.

I figured out the problem. It is in fact the light meter and not the camera.
I tested several cameras and all the f/ stops matched. I pulled an old meter(weston master) out of a box and it and the luna pro are off by 3 stops. When i bought new batteries for my luna pro, the guy at the camera store sold me VARTA V625U batteries which are 1.5V and not 1.35V as the meter manual states. I asked him if the difference in voltage would make a difference and he assertively assured me that the 1.5V are fine and are the replacements to the original mercury batteries. I then went to their sister store to confirm, and they said the same thing. However I remember buying Weincell batteries a while ago and they were 1.35V like the originals . So the guy at the store must have been wrong. I have to have a word with him. This could have f$@ked up my whole shoot.

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

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.

80! Wow...great stuff! Good thing I have f/1.0 and 1.1 primes, eh?
