Reciprocity characteristics of Fuji 50D

[emil_salek2]

Does someone still have in his/her files the reciprocity and CC correction tables for the discontinued Fuji RFP 50D film? While Kodak lists these characteristics even for older films, I cannot find what I need on the Fuji's site. When this film was discontinued I put these data sheets in such a safe place that I cannot find them anymore. Or was it my wife? :o)) Many thanks for your help.

I've checked for my older Fuji DataGuide, but have nothing around

here from before 1996. I'll continue to look in a few other places

and post again if anything turns up.

In the meantime Emil, if you have enough film, I suggest you use a

few sheets to do some tests. RFP did not keep well, even at 0

degrees F, always tending to go magenta as little as one year past

its expiration date. Long exposures give green results. If you have

lived a good clean life, the work you intend will require exposures

exactly long enough for the magenta and green to balance perfectly!

Sorry to have taken so long. I use a storage cabinet at work to keep

old documentation. For the last few months I've been working on a

project at a location remote from my regular office, and only this

morning was able to access my files to do your research.

From a 1991 RFP Technical Data sheet:

 

<p>

 

1/400 - 1 sec: no correction

 

<p>

 

4 seconds: 5M, +1/3 stop*

 

<p>

 

8 seconds: 7.5M +1/2 stop*

 

<p>

 

16 seconds: 10M +2/3 stop*

 

<p>

 

32 seconds: 12.5M +1 stop*

 

<p>

 

64 seconds: Not Recommended

 

<p>

 

*includes filter factor

Performing a test would still be wise since RFP does so poorly

(becoming magenta) in long term storage.
