It was forecast to be a clear sunrise on Monday so we walked through to the Thames around 7am. These images are in order and show how the colours changed towards pink with direction of view and as the cloud built up. The exposures (for future reference!) in sequence were 20 secs, 20 secs, 6 secs, 1.3sec,1.3 sec and the rest 1 second, all at f22 using live composite mode on the Olympus EM1 II - I didn't record how many exposures each had - obviously more where there were changes in the highlights being added as with reflections or contratrails. Not sure what passed behind St Pauls and left a dotted trail (?ideas)
