This was one of the strangest days in terms of sky and weather that I had in Barcelona. Half my photos have lovely blue skies on them and the rest have extremely flat grey skies. Well it was very hot in the mid afternoon sun, but I took the cable car up to the castle at Montjuic and then walked back down into the city centre via the harbour. Using Photoshop, the above photo has a mock neutral density graduated filter (levels adjustment layer) applied over the sky. It may look a little false, but it does improve the image a great deal in comparison to what came straight out of the camera.
