[The Pavillon de Flore and the Tuileries Gardens]

Taken in September 1849 from a window of the École des Beaux-Arts, this daguerreotype exhibits the dazzling exactitude and presence that characterize these mirrors of reality. True to the daguerreotype's potential, stationary objects are rendered with remarkable precision; under magnification one can clearly discern minute architectural details on the Pavillon de Flore, features of statuary and potted trees in the Tuileries Gardens, even the chimney pots on the buildings in the background along the rue de Rivoli.
Daguerre himself had chosen a nearly identical vantage point in 1839 for one of his earliest demonstration pieces, and it may well have been with that archetypal image in mind that Choiselat and Ratel made this large daguerreotype a decade later. Choiselat and Ratel, among the earliest practitioners to utilize and improve upon Daguerre's process, first published their methods for enhancing the sensitivity of the daguerreotype plate in 1840 and had achieved exposure times of under two seconds by 1843. Unlike Daguerre's long exposure, which failed to record the presence of moving figures, this image includes people (albeit slightly blurred) outside the garden gates, on the Pont Royal, and peering over the quai wall above the floating warm-bath establishment moored in the Seine. Still more striking is the dramatic rendering of the cloud-laden sky, achieved by the innovative technique of masking the upper portion of the plate partway through the exposure.
