[Leica] Slides from color negatives

["Roy Zartarian" <rzartarian@snet.net>]

LUGs,

I'm jotting down my experience with Kodak SO-279 Vericolor Slide 
Film in the hopes that someone on the LUG may someday find it 
useful. SO-279 is designed specifically to produce positives from 
color negatives.  It appears to be a fine grain color negative film 
without the orange mask.

I recently exposed and processed several rolls of the film in 
preparation for a talk and slide show which included images 
originally taken on color negative fim.  The occasion was one where 
I could not take the digital approach.

Kodak's documentation is a bit sketchy especially for exposing the 
film with a camera.  Through experimentation, I found that rating 
the film at 2 or 1 for TTL metering worked best.  With the R8, I set 
the ISO to 8, then added +2 or +2 1/2 stops with the exposure 
compensation lever.

The film calls for a tungsten light source, so I used the focusing 
light of a Bowens Illumitran for illumination.  

For filtration, I began with the 20M and 30Y as indicated by Kodak, 
then adjusted the pack according to the changes printed on the 
film carton.  In my case, the carton indicated +5M and +15Y, so 
my final filtration was 25M and 45Y.

The camera set up was an R8 body, viso-to-R adapter, focusing 
bellows 2, and a 50 mm Nikkor enlarging lens.  With everything in 
place and the lens stopped down to 5.6, I set the R8 mode to A 
and let the on board metering do the exposure.  I bracketed by 
increasing the exposure in steps to +3 stops.

Since I was using bulk loaded film, I knew the local Cheapco 1 
hour lab was out of the question.  Turnaround time was also a 
consideration so I did my own C41 processing with the Jobo.

The color and resolution of the results were most acceptable once 
individual frames were placed in slide mounts.  The processed film 
base is clear and the unmounted images did not look quite right to 
an eye accustomed to seeing a positive framed in the black base 
of E6 film.

Granted, an original transparency would be better and as 
circumstances permit I am making replacement images on real 
slide film.  But as a stopgap measure, this stuff worked.
