China girl, leader ladies, LAD girl or laboratory aim density (LAD) test film, is common name for a color chart test film with a color or black-and-white set up chart and a woman.^{[citation needed]} This would be used stand alone or placed on a film leader, that is at the start of the first roll of film. An LAD patch is neutral gray, with visual density of 1.0. With the LAD patch is usually a white and black patch for white balancing films.

Color patches of blue, green, and red are used to check saturated colors. Grayscale chips are used to check for neutral color balance and correct contrast. While the face is used for color correct flesh tones, LAD film is a few frames or a loop of correctly exposed and processed negative film that is used by a film laboratory to set-up their analyzers. This is to ensure that the duplication and printing processes of the film is correct. ^{[2] [3][4]}
