Abstract: Embodiments of this application provide a picture transmission method and apparatus. A photographer inputs an operation instruction in a user interface of a first electronic device, to select a first picture whose imaging effect needs to be shared. The first electronic device processes the first picture based on specification information of a display of a second electronic device, to obtain each second picture and a posing score that are used to represent the imaging effect of the first picture. Then, the first electronic device sends each second picture and the posing score to the second electronic device, so that a user wearing the second electronic device can view the imaging effect of the first picture, and a photographed object does not need to move back and forth to the photographer to view a photographing effect.
