Precisely. I was on my convoluted way to the office (needed a change) and ready to make some shots in this area, not for the first time. What attracted my attention was the lady holding the balloons, which was the "unusual" element - most wedding shots take place under the Bir Hakeim bridge nearby, and involve white dresses and no balloons at all.
While composing, I included the building on the left, the tourists in the foreground that could not be avoided, etc.
The newlyweds did their business and turned their faces towards the tower, i.e. away from me, which I preferred because I was basically an unconcerned "witness". This is where I started clicking.
On post-processing, I found the aligned heads to be *the* unusual feature of this particular shot and decided to reframe to 4:3 format, to get rid of disturbing elements (in particular the vertical line of the building on the left), and get a "lighter" image.
The 4:3 format allowed me to keep the feet of the standing girl in the frame. This helps keeping this sloping picture in balance, so to say. I also had to slightly adjust the horizontals for that reason.
The other lines and angles, as described by Akira, then started to manifest themselves.
Further adjustments were a slight warming up of the colors, because the subjects are in the shadow and went blue-ish.
I also raised the shadows, maybe a little too much here. That part of the PP left me unsatisfied after several trials (in CNX-D). I also could not get rid of the CA fringes around the statues, which would have been a necessary step for a big print.
