What should one do when one went to the city to shoot the sunrise and it rained? Go into the metro and take photos there :) Prague metro around 5:30 is nice and empty and you can take as many shots as you want. During the morning shoot I took this photo I actually visited three different metro station in under 30 minutes. Just always took few photos and moved to the next stop.
This is a manual blend from 5 exposures, taken at the Náměstí Republiky metro stop in Prague.
