Settings for lowest noise?

I got a Century Tru-Pol polarizer, and it happens to be an 85 polarizer


Barry - if you have a moment, could you give us a link to the Century filter you're talking about?

I looked around, and found the Century (Schneider) Tru-Pol filters, but I didn't find anything that listed it as being an 85 filter as well (seems like the kind of thing they'd mention).

Just want to make sure I'm looking at the right filter here.
Thanks.

Seems like Barry's list of gamma setting with the least to greatest noise is basically just a list of gammas from more crushed to more elevated blacks or more precisely more elevated black stretch.
So yeah, you see more noise if you raise the shadow detail.
I don't think there is anything more technical going on than that.

While we're on the subject, RE Snader in San Francisco had a shoot out with all the latest & greatest cameras today & yesterday. I didn't directly compare the HVX to the Canon & JVC because they were on other sides of the room, but I did look closely at the HVX & ran into the same monitor as a a Varicam. I had just taken possesion of my HVX that morning and was having buyers remorse & fear until I looked at that camera. It's a great picture.
Noisier & grainer than a Varicam - yes, but noisy? I'd say no. Granted they had detail set at -6 probably a little low, but I thought the noise issue was nonsense.
It is what t is - a 1/3" chip. Noise is probably similar to a DVX. But I wouldn't hesitate to shoot it at +6 if I needed the stop on a doc or even night shoot on a feature if I had to. Even +12 was not as bad as I expected.
Very briefly turned a JVC onto +6 and it looked like golf balls, but it was a different monitor and I didn't spend any time with the camera, so don't take that too seriously.
(I did see some beautiful dramatic footage shot on the JVC at one of the seminars. Very well lit though.)
 
Alright - I realize I'm really splitting hairs here - but I'm just curious
(this is the first time I considered using an 85 series filter to correct for daylight... I've always just used the 56K WB setting instead).

I was looking around, and ran across the Hoya 85 series, and they are listed as follows:

85 SERIES COLOR CONVERSION CHART

An 85 decreases the color temperature from 5500-3400 degrees Kelvin
An 85A decreases the color temperature from 5500-3100 degrees Kelvin
An 85B decreases the color temperature from 5500-3200 degrees Kelvin
An 85C decreases the color temperature from 5500-3800 degrees Kelvin


So given that the WB prsts on the DVX are 56K and 32K,
wouldn't it make more sense to use an 85B filter, as opposed to an 85?
Or possibly even an 85A?

Hey, I already said I was splitting hairs here.
:) Just curious, that's all.
