Oh hell yeah! Judging only from the shadows on the buildings and the approximate season in that small photo (small as displayed), I could guess "sometime in the morning" but within five minutes?! That's pretty good.
I have to admit I didn't quite use the photo displayed. If you go to Google Images and search "Richard Dunn Greenwich", the same photo comes up several times, about four times the area of the one displayed, but still not big enough to read the watch. That was good enough to get a good shadow from the west tip of the East Wing of the Queen's House Complex, and to note where the shadow intersected the row of arches. I then found the same points on Google Earth and enlarged the view to maximum size. I measured the bearing by sliding a Douglas protractor under a transparenr plastic ruler held to join the two points. Although I quoted the shadow as 315(T), Zn Sun was the reciprocal 135(T). DaveP
