"It’s not that she could really have passed for a pre-pubescent girl—she didn’t skimp on the lipstick or mascara—but she exuded a childlike quality that made the illusion work well.
Slightly oversized sets, clever camera angles and tricks, such as having other cast members stand on boxes, added to the illusion that the 24-year-old actress was only 11. Moreover, during filming, Pickford discovered by chance a lighting effect that made the illusion even more believable. Light hitting a hand mirror on her dressing table illuminated her from below, taking years off her face. When she told her director Maurice Tourneur about it, he was skeptical but Pickford insisted on having a scene shot once with the lights set up in the traditional way and once with them set up in the new way. The effect was striking and the “baby spot” became a standard lighting technique throughout the industry." - The Poor Little Rich Girl
More literally than this.
