Tidal freshwater Forth topsy-turveyed

I spent today out at Stirling University's campus on day 1 of a 2-day First Aid at Work. My bike ride home took me over the tidal River Forth at Cambuskenneth where I took this photo of the ebbing tide. But, 'fessing up, it isn't quite what it seems. It is upside down, giving a strange effect, making it look like the surface is being viewed from underwater, albeit water that would be much clearer than the silty estuary water! I quite like the effect.
