Using time-lapse photography, Sunlight in an Empty Room (Emily Dickinson's Bedroom) documents the daylong path of sunlight as it traveled across the bedroom where Emily Dickinson lived her entire life, much of it in seclusion. Equally invested in the phenomenal and the psychological, Spencer Finch finds a touchstone in Dickinson, whose poetry is a testament to the mind's ability to create an internal world far more vast than the external one.
