I made the tubes and everything worked well, except for the holes in the emulsion. I can't figure out how they got there. I suspect one of them happened when i removed the film since it is roughly the size of my finger tip and right at the top edge of the edge. The others are a complete mystery since they would be at the bottom of the tube and away from my finger. They are also in different spots on each neg. They are too big to be pin holes. I fixed the three negs in different trays, so that is not the problem. Has anyone else damage the emulsion of a neg getting it out of a tube? Yes, the emulsion was to the inside of the tube, and was not touched at all.
