    In this paper, we describe a method for creating all-in-focus photographic images where all of the subjects are in focus as much as possible from partially in-focus photographs with only its subject in focus when photographed by a camera with manual focus. Usually, the focusing range and the depth of field are wide, but become extremely narrow for nearby subjects. Consequently, it is difficult to photograph many subjects in focus in closeup photography. In this paper, we can combine the transform coefficients using wavelet transforms and easily create photographic images with natural focus but without noticeable seams.
