How Do Impaired Artists Positively Illustrate Aspects of Disabled Life?

In "Disability", Nancy Mairs reveals that the media denies "the existence of [her] ... kind absolutely" (14).  Although it is true that "disability ... may enter anybody's life" at any time, I researched and discovered that there are impaired artists that positively illustrate aspects of disabled life, in particular the blind photographer Bruce Hall (14). 
Curator Douglas McCulloh explains Bruce Hall's purpose for practicing photography with an antimetabole:  "Most photographers see in order to photograph.  Bruce Hall photographs in order to see" (McCulloh 34).  Bruce Hall, born with multiple, serious eye conditions, loves photography and "has constructed his world from photographs" (McCulloh 34) because it enables him to have "a strange form of double vision" that he calls "'intensified seeing'" (McCulloh 34).  This double vision comprises his mental impression of his subject and the actual photographic result of it.  Hall's photographs are mainly glances into the underwater and the "autistic worlds", because he believes that "One can visit, gather glimpses and impressions [of these worlds], but it is impossible to truly inhabit either space" (McCulloh 34).  Two of his photographs that intrigued me are Silhouette, an underwater photograph, and Aberration.  Silhouette, an underwater photograph, depicts the serenity found in the subsurface world, and Aberration is a perception into the visualization of autistic children of water droplets.
