Thank you for all of your comments, and taking the trouble to reply. As to the pole . . . well, it didn't bother me at the time so we'll let it be. This is an industrial landscape, in fact, so it is not out of place. This was at one time the centre of the most important copper mining area in Cornwall. Those stones in the foreground are the supporting granite "setts" for the rails of a horse-drawn tramway which carried the copper ore to the sea, so for my purpose (which at the time was a magazine article on early railways) they were the subject.
When I pulled the film out of the spiral I could see straight away that I had done something horribly wrong. There was a light under-developed strip all the way down both sides of the negatives, and I very nearly just binned them there and then as I could easily re-shoot the subjects. But I stayed my hand, and this frame turned out quite well in an Edgar Allen Poe sort of way. Never did get that article published, though . . .
