“In a magazine or on the Internet, find one fashion shot, a beauty shot and a portrait shot and explain how you think the lighting was set up in each shot.”
Beauty: Main light on the left side of the camera (but close, not on the subjects left side) and fill light on the right side. (Photo Rossella Vanon)
Fashion: Main light on the right side (front close to camera). Looking at the shadows on the models left arm vs the shadow on the dresser she is leaning on I can tell there is a backlight on the left back side of the model. If not, her left arm would be as dark as the dresses.
Portrait: For this one I think the main light on the left side and some sort of fill light maybe on the right front side to make the shadows less dark.
