I hope this doesn't mean we can't make further comments about this very nice photograph. I looked up Zero image pinhole cameras and see that they do a 5x4 with stacking sections, which presumably allow you to change the width of view -focal length - of the set-up. I wonder if this was what you used Martin, and if you had used a lens, what focal length would it have needed to be to get the same width of view as you achieved in the photo. And further, you are getting something here that you don't get with a camera with a lens. And I don't just mean an overall lack of sharpness. Can you tell us how you see it? What do you feel you get from a pinhole photograph like this when you look at the original photograph, that you don't get with a conventional photograph?
I have never got into pinhole photography, but I do have a precision pinhole, acquired several years ago, and would be happy making a suitable box to mount it on. Having seen other excellent pinhole images by Martin, I would be happy if he could offer me some advice on the way forward here.
