I do big cities from time to time, but I do not consider myself as the typical cityscape shooter. I love to do interesting architecture and a bit street photography (difficult to use commercially nowadays to many issues with property and model releases) and if I do cities I have my shooting plan. I have my list of locations with ideas at what time a location would be best. I also choose my accomodation according to my shooting plan.
This time was different, Buenos Aires was meant to be a kind of vacation between Subantarctica and the Altiplano. Of course I shot a couple of hundred frames, but I behaved like an "ordinary" tourist. I took just my small mft camera with one lens, no tripod no nothing. We let us drift through the city and it was big fun!
