I thought this excerpt was interesting:

In 1839 William Henry Fox Talbot coined the phrase “the art of fixing a shadow” to describe his negative-positive photographic process that became the basis of the photographic medium. Since then critics and historians have written at length about the metaphorical role photography plays in preserving the past and halting the fleeting moment. Childhood is a very brief period of personal development and discovery, perhaps even more so for Guille and Belinda where the onset of adulthood comes at an early age. The enigmatic dreams and fantasies from the fertile imaginations of Guille and Belinda might have gone unobserved if not for Sanguinetti’s efforts. Through this archive of images, which are as inexplicable as the imaginations that choreographed their content, this fleeting shadow of youth is preserved.
