When I first saw this composition, I was initially reminded of the "ESB 316" image by Joel Tjintelaar (hence my tongue-in-cheek title). However, if you are familiar with that shot, you can clearly see my final image has gone off in a whole other direction.
First of all, I was unable to get a symmetrical viewpoint of these two towers. I had to shoot from a walkway between the two buildings, but the walkway was not completely central. Even getting as close to the edge of the walkway wasn't close enough. Consequently, when processing the image, I felt I needed to twist it a little to avoid that 'almost symmetrical' issue.
Then, I really wanted to make it colour, even though it is not particularly colourful. While I admire all those black & white long exposure architectural photos out there, I feel that I need to do something a little different, and feel the urge to inject colour into that genre.
Any way, the photo has taken a life of its own compared with what was originally envisaged. Personally, I tend to find that happening for most of my better shots. And those that I plan out tend to end up a little disappointing.
