Cameron's work was contentious in her own time. Critics lambasted her softly focused and unrefined images, and considered her illustrative photographs amateurish and hammy. However, her portraits of respected men (such as Henry Taylor, Charles Darwin, and Sir John Herschel) have been consistently praised, both in her own life and in reviews of her work since. Her images have been described as "extraordinarily powerful" and "wholly original", and she has been credited with producing the first close-ups in the history of the medium.
