There is always something satisfying about seeing lines, whether it be implied lines or geometric lines. No matter where your go they are always there but vary dramatically in form.
I visited London for a couple of days and was taken back by the amount of photographic opportunities. It was one of the few times where I could photograph in bright sunlight an not mind about the harsh shadows created by the buildings. In a lot of cases it helped to enhance the strong architectural designs.
Overall, it was just nice to be able to go out with a camera body and a couple of lenses and just enjoy.
