I apologise that this is an odd PaD, but I've never come across this before and thought it fun to share. I came across this artist site and found a strangely familiar image, one I'd taken some years ago....
2012 -
I've spoken to the artist (and wish her well with her artistic endeavours) who said she had come across the image on the internet, was looking for one to do to be presented to the ship and couldn't see anyone's credit with it, and that anyway RN ship photos are the property of the Navy! It's a work of minutes to id the image via google as mine, and the second point is laughable. Anyway to cut a long story short I said I was OK with the use in exchange for a print of the painting, but it's a first for me :) I suppose it's more ironic that a copyright watermark is emblazoned on the picture thumbnail!
The artist also missed the link on the following page!!: which is titled Ian Clowes collection and has rights statement and pbase links at the bottom - the maritime quest site owner had asked permission by the way...
