Cheers, Rob. I just did a search, something I hadn't thought about doing before now, but probably should have. Apparently he's a local chap from Pakefield called Malcolm Wright. This portrait was taken by a well known local photographer called Gillian Allard.
This does potentially open a bit of a can of worms and leaves me feeling slightly uneasy. This image of the old man 'peering out' of the tower is my take on what I saw but, of course, the portrait belongs to Ms Allard...
I'm absolutely sure you are not the first or last to capture that image, or even change it (b&w). Anyone who puts their art out there must surely give up some control over it?
