I found this an interesting challenge. Due to a busy schedule, I wasn't exactly sure where I would be at 5pm, but there was a good chance that I would be passing through the centre of Sheffield. I knew it would be dark, so I packed my lightweight tripod as well as my camera.
At about 4.50pm I got off the bus near the BBC's Sheffield studios. I had an idea: I could take a photo of the illuminated clock outside the studio building... but, unfortunately, I found that it wasn't illuminated on this particular occasion.
As the minutes ticked away I picked my way through the ever-changing obstacle course outside Sheffield station. The moon was rising over Park Hill Flats, providing a perfect backdrop to the rush-hour chaos.
In a flash of inspiration, I spotted an ideal vantage point outside entrance to the Showroom Cinema. I very nearly didn't get there in time thanks to the numerous barriers designed to corral pedestrians and steer them away from the roadworks.
