Proudgeek's request to tap my brain about shooting in Barcelona got me thinking. I am sure that other people would see a benefit from a discussion like that. So why don't we have the discussion where everyone can benefit and chime in.
One of the first things I like to do when I arrive in a new city is to go to my pre-researched sunrise and sunset locations. A good choice for a sunrise is on Montjuic, the small mountain overlooking Barcelona where the Olympics were held. Specifically, I was on the north-east corner of the hill along Miramar street, next to a very large hotel, where I had an excellent view where I caught this image at blue hour of the sun just before it started rising over Barcelona's harbour.
As the morning progressed, I turned my attention to the north and captured this image of Barcelona's cathedral at golden hour.
