Filters

[Tom Hepburn]

Hello all,

 

As I mentioned in a previous post I have a Kodak K-100 Turret camera with 3 lenses:

 

Elgeet 2" F:1.5 Cini Navitar

Elgeet 3" F:1.9 Cini Navitar

Berthiot Cinor 1.8 F:2.5

 

I'll be shooting Vision 2 200 and 100 and B & W 64.

 

I know for shooting color outside, I'm going to need to get an 85A filter. I've also been told that I would need a high density filter if the sun is really bright (for B & W as well). In my limited search it seems like it's going to be difficult to find the right size/type filters for the three lenses.

 

I have two questions:

 

Should I consider this one size fits all solution (and will it work on my 3" lens):

What if I need to use both the 85A and the high density filter at the same time? Also, are there any other filters I should be considering? I may shoot some inside as well.

 

Thanks,

Tom

While a one size fits all solution is fine, series adapters would be more practical.

 

The fast 50mm will need a series VII which is around two inches in diameter.

The 25mm will work with something smaller like a series V, but the smaller sizes are tougher to find these days.

 

retaining rings with threads on each side will allow you to stack.

 

You can get combo 85 and ND filters. For B/W a yellow and a red are usefull.

Try adorama too.

Thanks Leo,

 

So is most everyone here using a ND filter when they shoot outside?

In bright sunlight at f/16, the shutter speed required is the reciprocal of the ISO rating. But at 24fps your shutter speed is only 1/60. So you're OK with the 64ISO, but you'd need nearly f/32 with the 200. So yes, you need some ND, especially if you want to control depth of field.

The square filter holder will get in the way of the other lenses on the turret, if you want to change quickly. So you'll probably be better off with screw-ins. Buy the largest size you need and stepping rings for the other sizes.

OK, so I just got back from two of the biggest "film" based camera shops here in Chicago and we could not find a filter or adapter to fit the lenses on my camera. They are approximately 45mm and 51mm. So that's not good news. Apparently they may have been a part of a certain "series" of lenses produced by Kodak or the lens manufacturer when the camera was produced 50 years ago.

 

BUT, I did have an another thought as I'll be having the film scanned for the computer. I am a seasoned user of AfterEffects

( http://www.adobe.com/products/aftereffects ).

For those of you who are familiar with this product, is it possible to compensate for shooting without a filter (either insider or out)? It can't bring something out of nothing, for example extreme overexposure or underexposure, but it does seem to work well with adjustments.

 

Any thoughts along these lines would be appreciated

You need an 85B filter actually, not an 85A, to correct 5500K to 3200K. Though many times an 85B filter is referred to as the "85".
