Let There be Light, by George Grey Barnard, at the gravesite of Isaac W. Bernheim, his wife, daughter and son-in-law.
I don't know if there is a photographer's prayer but, if there is not, "Let There Be Light" would be a good one. The words are engraved on the base of the statue.
At the top of a hill and behind the statue ("Let There Be Light" by the artist George Grey Barnard), Isaac W. Bernheim, his wife, daughter and son-in-law are buried on the grounds of Bernheim Forest. Not a bad place to spend eternity.
