 Researchers predicted that participants would prefer artwork that was lit from the left side and when given the option, they would choose to place lighting on the upper left side of a piece of artwork.Participants found paintings with lighting on the left to be more aesthetically pleasing than when it was lighter on the right side and when given the opportunity to create light on an already existing painting.The left cheek bias occurs when viewers prefer portraits with the subject displaying their left cheek, while those that hold a right cheek bias prefer portraits displaying the right cheek.
