A photo of the Eiffel Tower at midnight, during my first visit to Paris.
Initially, I was proud of myself, having set up a tripod, being patient for about twenty minutes, snapping multiple shots, and eventually capturing the photo I was trying to get. So when my camera died seconds later (having been used all day by yours truly) I wasn't too worried about it.
Little did I know at the time, the Eiffel Tower gives off a dazzling light show every night, causing this moment to, quite literally, pale in comparison. Of course, this happened a few moments after my camera died.
Although I did enjoy the spectacle, something inside of me was "tsk, tsk, tsking".
