A digital photographing apparatus capable of acquiring data about an image having a wide dynamic range and a high grayscale resolution, a method of controlling the digital photographing apparatus, and a recording medium storing a program to implement the method are provided. An embodiment includes an imaging device that acquires a reference image and additional images at different exposures and a multi-level threshold map generation unit that classifies the pixels of the images into levels according to brightness. The embodiment further includes a motion data acquiring unit that acquires motion data for each pixel based on its respective brightness level and a first weight data acquiring unit that acquires first weight data based on the motion data of each pixel. In addition, the embodiment includes a final image data acquiring unit that synthesizes the pixels of the reference image and the additional images based on first weight data.
