As Bullock continued to work within the Photographic Society of Philadelphia, he became affiliated with the “New School” of photography, which focused on creating soft-focus images that were considered more impressionistic. Bullock was a founding member of Alfred Stieglitz’s Photo-Secession in 1902, which was dedicated to advancing this “New School” of photography. He remained active with the group until 1910 when it gradually disbanded.
