Abstract:
1. A digital photographing apparatus comprising: a display unit for displaying a captured image; a position setting unit for setting a position on the display unit; an area setting unit for setting an area based on the position set by the position setting unit; a photometry unit for measuring luminance of the set area; and an exposure value determination unit for determining an exposure value based on i) a photometric reference, which allows a value obtained as a result of measuring the luminance of the set area to be a reference value of a high luminance area of luminance distribution according to an exposure amount of an image, and ii) a result of the measuring performed by the photometry unit; wherein when a reference reflectivity is 18%, which is an average reflectivity of a general object, and when luminance of the average reflectivity is set to be in a range of 115/255 to 128/255, which is a range of luminance according to the luminance distribution, the reference value is set to be in a range of 190/255 to 255/255 of the luminance distribution.
