Hi Richard! If anyone has a Photo-Lab-Index
or Agfa data sheets from the era, it'd be interesting to
see a graph of the
curve.
Best, Rich
I think I have a Photo-Lab-Index of the right vintage
but I don't remember it having curves in it, I'll have to
look. I also have somewhere some Ansco and Agfa data
booklets. I think they are in a file cabinet which is in
storage right now. I am pretty sure those have curves.
It seems to me that even Agfa variable contrast paper
would reach higher contrast than others. I used it for
rescuing very underexposed negatives at times. Not wonderful
prints but would make a recognizable image where nothing
else would.
Its too bad that Agfa could not find someone to take
over their photo products division. I think the problem with
both Agfa and Kodak was that they were too big to shrink and
still be at all efficient.
The effect of digital technology on chemical
photography reminds me a bit of the shift when
diesel-electric locomotives supplanted steam c.1950. There
were three large companies who made steam locomotives, none
survived the changeover.
