Fine art photography refers to photographs that are created in accordance with the creative vision of the photographer as artist.
Until the mid 1950s it was widely considered vulgar and pretentious to frame a photograph for a gallery exhibition. Prints were usually simply pasted onto blockboard or plywood, or given a white border in the darkroom and then pinned at the corners onto display boards. Prints were thus shown without any glass reflections obscuring them.
Steichen's famous The Family of Man exhibition was unframed, the pictures pasted to panels. Even as late as 1966 Bill Brandt's MoMA show was unframed, with simple prints pasted to thin plywood. From the mid 1950's to about 2000 most gallery exhibitions had prints behind glass. Since about 2000 there has been a noticeable move toward once again showing contemporary gallery prints on boards and without glass. In addition, throughout the twentieth century, there was a noticeable increase in the size of prints.
