As mentioned in the comment. The Asakusa one was pure luck. We did nothing to enhance the image other than slightly rotate it (and I mean slightly). The Yasaka one we were taking a lot of over exposure pics throughout that shrine. We've got some nice ones but that one was probably the best. The K's House staff member said that those Shrine gates are meant to be a gateway from the real world to a sacred place, so the barrier of light that was created from the overexposed traffic helped to show the chaos outside and the calmness inside.

All of these were flukes. We were just after some nice shots, they turned out better than we had expected.
