An image maker should always try to return to the 'scene of the crime' or should I say 'the capture'. This means you can refine your approach and look for opportunities to perfect the image. I was visiting Shanghai on business and I went down to the waterfront in the mornings to make images of the sky scrapers along the river. On my early visits, I noticed that all the photographers were stuck against the railings making images of the skyscrapers, I wanted more context and I really liked the lines of the darker pavement stones that could be used as visual cues to make strong diagonals in the foreground. Symmetry here was key to the setup. It really helped that my hotel was only 5 minutes walk away, I kept an eye on the lighting conditions every morning, if it was really dull and overcast I didn't bother going down. My initial visits enabled me to sort out my approach and composition, I was just waiting for the right lighting and fog/smog. On the day of my departure I was lucky enough to have just the right amount of smog, fog and sunshine. I was also fortunate that there was a platform above the parade which enabled me to get a strip of the silver river between the parade and the backdrop of the rising towers. The smog held the sunshine back sufficiently to impart a softness to the scene. Time was of the essence as the sun was rising rapidly into a patch of bare sky.
