Looking north along the Forth Bridge
After a while playing with photographic filters on the pier I moved the group around to a spot to the East of the bridge so we were at least facing the right direction for any sunset, not that we still thought there was going to be any sunset to write home about.
After about 20 minutes at the new location something started to happen. There was colour in the clouds, subtle but there, mainly purple hues. At this point the water was like a mirror and that colour just kept intensifying, I remember looking west towards Hound Point and seeing the colour extend all the way, at which point it was clear this was going to be special.
