Here's a picture of the Ferris Wheel that has been in Liverpool city centre for the last couple of months. I initially went to try very long exposures of 20-30 seconds, but they didn't turn out as good as I expected. :-( I found that the short exposures of 1-3 seconds gave a nice effect with the patterns of the ever changing lights on each spoke of the wheel. No 2 exposures are the same because of the changing patterns of the lights.
