Here's what the fake 35mm Aerochrome film from @robinsonjake looks like when you develop it. Ugh. Here's what my lab wrote to me about this garbage:
"Peter... one of those rolls was definitely NOT aerochrome. Our best guess is that it was some sort of movie film, like Seattle Filmworks film. Not good... The black gunk is a remjet coating that comes off in the process the film is supposed to go through, in our machine it just makes a mess. We tried to clean the edge to find out what the film was, but can't find any edge printing." In short, don't be deceived by this fraud and scam artist on Ebay or Etsy. I waited too long to get my first roll developed and so did not find out it was fake film until it was too late to file a claim with Ebay and get my money back... BUT, I was lucky enough to get my $400 back from the second transaction and Ebay agreed that they have received numerous complaints about this fake film.
