I just got my hands on a pro-pack of this, but have been unable to find any information on it at all on the web. It is 30 years(!) out of date but I thought it would be fun to try. Does anyone have any experience with this film? Did it resemble Royal-X or Recording Film? Rate it at what? On the box it recommends Atomal or Refinal. Any info would be of great help. Thanks.
