'INSIGHTS,' an annual juried show, presents the work of legally blind artists whose diverse conditions and approaches to their art present a rich exploration of the centrality of sight in visual art and its limits. Some make art to see what otherwise remains hidden from them. Pedro Hidalgo, who suffers from myopia, uses the camera to make blurry, distant objects appear clearer and closer. This process becomes a theme in playful self-portraits in which, wearing dark glasses, he struggles with similar techniques to compensate (or overcompensate) for the limitations of his vision. In Right or Left, he pantomimes driving a car while using a cane to find his way, while in Who the Hell Wrote This Anyway?, he reads a piece of matzo as if it were braille. For other artists, the disturbances in their vision have generated new ways of seeing the world despite the obstacles they otherwise present. Bobbie Gray, who can see only with his peripheral vision, constructs watercolor and collage landscapes by focusing on strong contrasts in color rather than on fine detail. In Loggia, the result is a diorama-like construction that doesn't have depth of field and gives the viewer a more immediate sense of standing amid bushes and trees. Other artists challenge the importance of sight more radically, emphasizing the roles of memory and imagination in their art and inviting the audience to touch the works and to explore with their minds rather than with their eyes. The show raises many provocative questions, such as What does it mean for an artist who "sees" only by touch to insist that "colors are very important to me"? Can the production of visual art be divorced from the enjoyment of looking at it? While the works don't deny the importance of sight in visual art, they bring to light the multiplicity of senses that visual art draws upon and intimate that the production and enjoyment of it requires at least a certain degree of blindness.
