The paper describes the depth of field simulation method applied to already taken photographs. It is consistent with the physical aspect of the phenomenon and bases only on parameters which are equivalent to the properties and settings of the digital camera. Author describes main depth of field basics and, taking into consideration digital photography aspect, introduces equations for circle of confusion estimation and further - four versions of blurring algorithms with different computational complexity and advancement level. The potential user of the implemented method can test individual camera setup and/or learn how each of its elements influences the depth of field effect on an image, without any knowledge about image editing methods or geometrical optic physics required.
