Hi,
Does anyone have experience with this color negative film, I just aquired two 5 in x 50ft rolls with a view to slitting it to roll onto 122 size.
My question is what is its ASA/ISO rating? Given that it is 1990 stock I will give it about 3 stops more than its rating but unfortunately I can't find a starting point anywhere. I found that it can be processed using C41 chemistry and some other tech info on spool and thickness etc but not the ASA rating.
The only tech sheets I can find are on aerial B&W and aerocolor III and IV and the duplicating films, as far as I can ascertain SO-200 film pre dates these films.
Failing any more info I will probably start testing it at ISO 25 or 50 given its age - if it was originally 200 for example.
Thanks
