Provided are a digital image photographing apparatus which easily captures an image of a composition intended by a user, a method of controlling the apparatus, and a recording medium having a program for executing the method. The apparatus includes: an image capturing device for receiving light to generate data on an image; and an auto-focusing tracking unit for allowing a lens to be auto-focused on a subject selected by a user. The image capturing device generates data on a still image when the subject on which the lens is auto-focused is located in a predetermined region of interest (ROI).
