In Topic: Question about refrigerated film stock

04 January 2018 - 01:45 PM

I keep my film always at -18 degrees Celsius.

I've been told by the most expert for film postproduction in our country, that in those temperatures, the aging of emulsion is so slow, almost  negligible.

When I want to use it, I simply put stock from fridge to refrigerator for one day (when I have time ahead), or in emergency situations I just put in on a desk (+20 degrees Celsius) for a 2 hours a then load the magazine.

I have done this procedure many times and never have any issues with frozen gelatin or whatsoever.

 

I have stored exposed stock in refrigerator for a couple of weeks (6-8) and scanned image has been great! No lack of contrast, or anything.

 

Also old stock is fully usable, just overexpose it a bit.

I use to rate fresh new stock 1/2 EV slower (for better saturation), 2-4 years old stock 1 EV slower, and even older stock about 1 and 1/2 EV slower.

Film stock can easily handle overexposure. I've seen accidentally overexposed whole roll of fresh stock by 2 EV stops (wrong rating in exposure meter), and nobody in scanning room can see the difference from other rolls of project. Nothing was blown away.

So don't be afraid of older stock, just rate is slower and give it a lot of light.


In Topic: Arriflex d-21 useful in 2017?

30 December 2017 - 05:32 AM

Hi there,
I have got one D21 too and I love this little camera! Optical viewfinder with Arriglow is absolutely fantastic thing. You can even follow focus with it easily.
What I like is how good white balance system works - camera is in changing temperature (like from -5 to +25 Celsius), there is infrared polution, sun is changing - you just hit 5600k and it still looks, as it should look like! Although, we all know it is not just fixed at 5600k, but it is constantly shifting a little bit.
I don't know how it's done WB in Alexa, but on RED's and Blackmagic's cameras it definitely don't works like that.

The dynamic range (10 stops) and ASA 200 is a little drawback in 2017. And with sensitivity, for day exterior I rate it as 200, but for interior I use 125 or 100 rating for better noise floor.

Have anyone used anamorphic viewfinder with the camera ?
I'm trying to buy one for years, but that thing is no-one selling. I don't know, if it's the same viewfinder as for 535 (Arri AVF-1), or it is some special piece ?

Also I can't attach optical videoassit from my 435, there is some small missing piece to connect video camera (attached to the viewfinder system), to the side unit (Arri IVS-1), could someone help me with these ?
