Porto, Portugal, is one of my favorite cities. Whenever I am there, I like to get lost in its streets, and often it is before Porto itself wakes up. And on rare occasions when I find myself walking the streets during the day, I leave my camera in the hotel room. Instead, I use the iPhone and its incredible camera to capture a slice of this whimsical and wonderful city. Here is a subset of photos I snapped on a 36-hour-visit to this most lovely of all cities. All photos with my iPhone & edited with Darkroom App.
