Greenberg is credited by some within the commercial photography industry as having produced several unique styles that have since been emulated by other photographers. "Like LaChapelle and Avedon, Jill has pioneered a new style of photography, and her impact can be seen throughout the entertainment industry", the creative director of a Los Angeles creative agency told "Brief" magazine, with the publication itself characterizing her work as employing "distinctive ethereal backlighting." A president of NBC Entertainment Marketing who has employed Greenberg on a number of occasions due to what he terms her "distinct and innovative aesthetic" observed that "many other photographers follow her lead."
