May
Say cheese! May is National Photo Month (NPM) and is celebrated all across the United States. NPM was officially recognized by Congress in 1987 as a month-long event and the American Photographers Association is one of the primary organizations continuing the tradition. Individuals can explore the beauty and art form that is photography by snapping their own photos or viewing images at a nearby gallery.
