Abstract: The present subject matter refers to a controlling method of an electronic apparatus for long exposure photography in a multi-camera device. The method includes receiving first image frames at a first frame rate from a first camera of the multi-camera device, detecting a presence of at least one moving object in each of the first image frames, based on the detection of the at least one moving object in each of the first image frames, utilizing a second camera for receiving second image frames at a second frame rate, performing a motion analysis on each of the first image frames for selection of one or more frames among the second image frames, based on the one or more frames being selected, identifying motion gaps in each of subsequent frames among the selected one or more frames, based on the motion gaps being identified, generating one or more in-place frames, and generating a motion dramatizer image based on the one or more in-place frames.
