Our early photographers would be amazed by digital cameras that electronically record photographs and sound.They would also be impressed by two remarkable achievements in 1968: the Disabled Photographers' Society was created in England, and a photograph of earth was taken---from the moon! However, it is this writer's opinion that Rick Guidotti's photographs, and the organization Positive Exposure, offer a unique dimension in photography.Guidotti uses his camera to express the beauty of our shared humanity through people whose bodies appear different because of genetic diversity. Since 2007, Guidotti has been affiliated with ReelAbilities, film festivals that explore the experiences, perspectives, and art of people with disability.

When Alexander Wolcott received America's first patent for a camera in 1840, his accomplishment represented centuries of international achievement.Photography appears to have evolved from discussions of optics in China and Greece during the 4th and 5th centuries.As time passed, technology began to to express theory.The field moved in the direction of modern photography when British scientist William Hyde Wolloston received a 1806 patent for an optical instrument that used a lens. Later advancements in technology made cameras smaller, lighter, less expensive---and faster.In 1814,it required 8 hours of light exposure when Joseph Niepce used his "Camera Obscura" in France to make the first photograph: a building, barn and tree. Louis Daguerre's achieved the first fixed photograph in 1837 when, with less than 30 minutes of light exposure, he photographed a man having his shoes shined.In time, cameras became specialized in their function. There are cameras with wide angle lens for pictures of your garden and other landscapes. A camera with minimum focusing distance will capture your nieces' first smile with braces!. When the events in your life actually move as quickly as they feel--- a grandchild's soccer game!----, a camera with high shutter speed will record the action.The lens of a digital single-lens reflex camera (SLR) can be changed to suit the photograph.

Adaptive camera equipment enables people with physical, sensory and cognitive disabilities to communicate as photographers.For example, lenses with systems for optical and digital stabilization reduce the impact of hand tremor.Cameras with enlarged LED screens, and viewfinders that have diopter adjustment,are useful for some photographers with visual impairment. Adapted switch cameras will automatically focus and shoot images when a switch is moved.Cameras are tools of communication.
