Kodak Film

[claudio farkasch]

Hello

 

I recently got 1500ft of this Kodak film(2496 RAR Film, Estar-AH Base)

I allready searched the web but got no useful information on development

or ASAspeed.

 

if anybody of you got some info on this I would be very happy.

 

sure I could experiment with all of my chemistry(Microphen, Rodinal, Ultrafin

Liquid & SF), but a point in to the right direction would be nice.

I also got a book of how to mix kodak developers

I already found this post on my first search but it didn't helped me.

but maybe I just don't understand it right

It was an ISO 1000 film with a thick emulsion so the base was thinner. I used to dev it in D-76 and Diafine In Diafine I shot it at 3000-6000 But prefered it at 4000. in D-76 it was 1000 at 7 minutes but it is real old film and I bet Cosmic Fog has set in real bad. Inless it has been frozen in a cave I would not us Diafine but play around with Some D-76 and HC-110 infact the HC-110 may be much better for it.

I just got a copy of Kodak publication P-29, "Kodak 16mm, 35mm, and 70mm Films", from April 1975. It has info on 2496 RAR. The "Photorecording Sensitivity" is 125, and the meter setting is 80. By comparision, 2475 Recording had 1250 for both speeds.

 

Photorecording sensitivity is "Reciprocal of the tungsten exposure in meter-candle-seconds required to produce a net density of 0.10 over gross fog at an exposure time of 1/10,000 second, with rcommended development."

 

As for the description of the film, it is "Panchromatic with extended red sensitivity. Designed for high-temperature processing (up to 130 F) rapid-access negative processing. Can be processed to a reversal image. For use in oscillograph, cloud-chamber, modulated glow-tube, and other photorecording with all types of light sources."

ahhh

 

this explains something.

but i got it handled-the processing. I use tetenal Ultrafin with 1:10 and 10min in 68F/20C

but sometimes it apeares a little bit like a infrared film.

 

maybe I should try it with a red filter. and it is highcontrast

 

is there anything else interesting for this film on this infosheet.

could you mail it to me?

 

thanks by the way for your info.
