Hi Zainab - this is an interesting and unusual shot, and I think I have worked out what it is (I'll not say in case others might wish to guess.) I've wondered whether I should accept it into the Infrared-Club (Extra-Visible Imaging) as I'm not sure that it really shows that "extra" bit that the camera can see and we cannot. OTOH, it makes the viewer think as to what is going on.
Col
thank youuuu!
Cheers
