Digital portrait photo system is analyzed in the work. Technical and style development of portrait photography from its beginning in the middle of the 19th century till nowadays is shown. Different approaches to the portrait photography and portrait photography syntax are analyzed theoretically and through shouted photographs. Theoretically and through shooted portrait photographs the digital photo system is analyzed in all its elements � shooting, picture editing and realization (printing). In experimental part which is based on measuring and visual estmations influence of digital photo system elements on portrait photographs elements is analyzed. The quality estimation of final photographs are given on criterion of general quality criterion and on criterion of perceptual differences in comparison with portraits taken in �classical� photo systems. Changes in skin colors (in color photography) and tones (in black and white photography) through shooting with different lightings and ISO speeds, picture editing and printing in dominant digital photography printing techniques are estimated as well as influence of using image stabilizer system and choice of resolution, format and fines of image data storage in shooting phase. Through theoretical and experimental analyzes possibility of system optimization and choosing of optimal solutions and combinations in different elements of digital portrait photo system are shown.
