The city's photographic problem is not finding subjects — it is that every subject has already been photographed from the obvious spot at the obvious hour. The answer is the schedule: Place Vendôme and the Palais-Royal arcades at first light, the Seine's bridges in the blue half-hour after sunset, the Haussmann rooftops from a high window while the evening comes on. The middle of the day, when the light flattens and the crowds peak, is for editing, lenses, and lunch.
We position the base within a first-light walk of the Right Bank squares and a dusk walk of the river, arrange the high vantage points that need a request rather than a queue, and pace the week at two serious sessions a day. Paris gives a photographer more before nine in the morning than most cities give all day.
