The diagonals I found were predominantly man-made and within the built environment. Several appeared during my hunt for horizontals and verticals, often revealing the detailed structure of buildings. I was also fortunate to see Graeae Theatre Company’s outdoor performance piece ‘The Garden’ at the Southbank Centre in September. I was really pleased to get this image of one of the performers on her sway pole, hovering about the Southbank Centre. I particularly like the fact that you can see Waterloo Bridge and the London skyline in the background. It may be slitghtly more of a curve than a diagonal but it was one of the more unusual shots I took during this series of exercises.
