Like a lot of the most stunning, elegant wedding venues in London, Dulwich College in South London is grand, atmospheric – and very dark. This is a real challenge to a professional wedding photographer, who wants to create beautiful, bright wedding photography without resorting to unflattering flash. For this image, I positioned the bride so that she was illuminated by natural light coming in through the window. I exposed the image carefully to ensure that the background was also properly exposed, but maintaining the natural, low lit, look. Professional wedding photographers have to be good at capturing wide tonal ranges – from the intricate, delicate detail of white wedding dresses to charcoal morning suits – without under or over exposing any of the details.
