1. A photographing control method, comprising:
determining a first ratio, wherein the first ratio is a ratio of the current optical zoom ratio of a target photographic device to a maximum optical zoom ratio of the target photographic device;
determining a second ratio, wherein the second ratio is a proportion of an area of a person face region currently captured by the target photographic device in a whole captured picture; and
determining whether the first ratio is less than or equal to a first ratio threshold and the second ratio is less than or equal to a second ratio threshold;
if yes, controlling the target photographic device to perform optical zoom; and if
no, controlling the target photographic device to perform digital zoom.
