I spent the day wondering through the streets of Old Mazatlan and on almost every block, there was an abandoned house that had a window on the street that I could poke my camera through. It was sunny (always is in Mazatlan) and the lighting was very contrasty so it was a challenge to get good exposures of shadows & highlights. Multiple handheld exposures and some HDR with HDR Efex Pro plugin for Lightroom.
