How can this be? How can two negatives have thinner highlights, and the other five seem perfect? They're all printable, just seem to be developed differently.
Hmm ... off the top of my head, I would suspect the volume of chemistry - that might be a factor if it was roll film, but it is far less likely with sheet film in an expert drum. Difficult to say now, I would imagine, but were the highlights oriented toward the center of the tank? If so, volume might be the answer.
But then again ... It could be that static electric charges originating in the Crab Nebula were exceptionally strong on a day where there was a particular alignment with Venus and the Cygnus Galaxy....
