A lot of the films we see for sale now from the likes of Paul, Barry or Phil are often listed with the filmstock a title may be on, LPP poly or Eastman etc. These dealers are experienced and get the information off the film so when i buy, i am happy that is is what is listed.
A lot of money is being spent on new/newer products from the lab in Germany, Andec, bearing in mind its unlikely to still be around for 8 and 16mm in ten years time, about the same time it took for the crappy cheap fast fade Eastman stock companies use to use, to fade.
So this new stuff we are told is kodak low fade, hands up if anyone knows this for certain, and how do we prove it? Is it marked on the film or are we just told this and in for a shock ten years down the road. Some collectors may not give a monkey's, but i for one do.
