LOL. I think I've done those trails as well.
I have spent
the whole day scanning some ancient negatives. And I mean ancient. I think they may have been something my mom might have brought from her home when she married
? It's possible, that some of them might even be her father when he was younger.
They are of extremely bad quality, so I've had to fart around at great length with each image to actually get any degree of clarity....and I use the term loosely. So out of the whole day, I have only 8 'acceptable' images. (so far)
