1. An image photographing apparatus for proposing a human composition, the apparatus comprising: an obtainment unit to obtain an image having at least one frame; a decision unit to determine optimal composition information based on feature information that is detected from the image in association with a detected human region, including a face region; and a control unit to control a photographing parameter based on the optimal composition information, wherein the decision unit determines a shot type of the image based on a result of a comparison between a size of the detected human region and a size of a detected background region, wherein the shot type indicating a type of a shot represented in the image, wherein the decision unit determines the optimal composition information based on the shot type, wherein the decision unit extracts divided lines in the image, and determines the optimal composition information so that one of the detected human region and an eye region included in the face region is disposed on at least one of the divided lines, wherein the decision unit determines at least one of zoom information and location movement information based on the determined shot type, and wherein the control unit controls the photographing parameter based on the at least one of zoom information and location movement information.
