?Working in Africa opens doors of my subconscious more widely, my dreams are very vivid when I?m there,? says Viviane Sassen, whose photographs are on view as part of the New Photography series at MoMA. Sassen, who is Dutch, grew up in Kenya; lately she has used her medium as a form of self-analysis, creating graphic, color-saturated compositions that mine her childhood memories but also underscore her status as an outsider in a part of the world she will always consider home. In ?Alpha,? two young men cross paths in the street, but one, completely darkened to a silhouette, could be viewed as the wayward shadow of the other. In ?Parasomnia,? which is also the title of the series, a man who may or may not be asleep has tipped over in his chair, but Sassen has rotated the image so that he almost appears to be in free fall. ?I try to make images that confuse me,? she says. ?And I hope they confuse others, too.?
