I don't normally pay much attention to ghost photos, but courtesy of the SPR Facebook page, here's a discussion of one, taken at Eynsford Castle in Kent, on Robert Lea's blog: http://skepticsboot.blogspot.co.uk/2018/...nable.html
The puzzling thing is that his explanation rings true - that the "ghost" is just a window or door in the stone wall of the castle - but its position doesn't seem to match that of aperture he found in older photo of the same wall. I assumed there must be another aperture in the right place, which was obscured by another wall in the older photo. But then I found a third photo of the unobscured wall, and there was no such aperture there. So I'm not sure what to think.
