This is the harbour at sunrise when the moon was setting. I like to get out(when there’s no clouds) when the moon is just right to shoot! The moon can only be shot at certain times. The exposure of the moon is in a constant state of change,until it hits the blackness of night and than reverses the cycle when it sets in the west.
That is what is happening here.
The white boat in the background is the “Vargas Island”.
