Famous quotes containing the word photography:

    “Too many photographers try too hard. They try to lift photography into the realm of Art, because they have an inferiority complex about their Craft. You and I would see more interesting photography if they would stop worrying, and instead, apply horse-sense to the problem of recording the look and feel of their own era.”
    —Jessie Tarbox Beals (1870–1942)
