I must have looked out on the continuously changing skyline of the City of London thousands of times, but perhaps because I no longer pay daily visits to the office which offers this particular view over Waterloo Bridge, I do try to take a moment to appreciate it whenever I can.  So yesterday evening before I started a shoot there, I captured this scene illuminated by countless light sources, each with its own colour temperature, or so it would appear.  Inside the building the lighting was from a mixture of fluorescent, halogen and LED bulbs.  I'd love to know how our brains can adjust the colour of something we know to be white when we see it in reality, but can't when we see a photograph of the same thing.  It would certainly make photo editing a lot easier.
