Certainly possible if they are very nearly parallel to the film edge and the negatives are almost perfectly aligned in the scanner (a V500 would employ a film holder presumably), but I'm wondering if it could be a scanning issue? | |

If you do not completely rid the emulsion of K- or Na- thiosulphate fixer, the silver will react and slowly become a silver sulphide which will slowly fade whereas metallic silver is much more stable. Occasionally you'll see elderly prints that have "blacks" that appear mottled, brown and beige—that's what's happened. The same thing happens to film too. | |

Perhaps there was something in the cassette light lock fabric or film pressure plate. Check to see if the position changes. At any rate, make sure the film chamber is clear of anything. | |

I've been following the massive dev developing guides in the app for the film stock I'm using and have had much better luck with Kentmere 400, so I'm weary to deviate from those times, but I will definitely try a much longer final wash period with filtered water and possibly an acid bath for stopping instead of H20. Thank you | |
