 Stieglitz cited her, along with Gertrude Käsebier, Eva Watson-Schütze, and Mary Devens, as one of the ten most prominent American pictorial photographers currently working in an article in "Century Magazine" in 1902.Clark apparently learned some of her photographic artistry from Käsebier; later in her life she said she owed Käsebier for "any success she had with a camera".About 1920 she moved from Buffalo to New York City, where she advertised her portraits and other paintings for substantial amounts (up to $2,000 for full-length portraits).
