Macro Photography is a subject of photography in which the size of subject in photos is the same or greater than the size of subject in real life. One of the concerns in macro photography is shallow depth of field when taking extreme close-up image. The solution is to take a number of photographs with different focus field, then stack those images (focus stacking) into one image with large depth of field. <br /> <br /> When done manually, image acquisition with different focus fields introduces a new problem. Taking images with the same frame can prove to be very difficult because of the movement the photographer causes when changing camera’s focus field. To tackle that dilemma, a graphical user interface (GUI) system for changing camera’s settings remotely; and an image acquisition system for taking pictures automatically, will be built. <br /> <br /> In this paper, we will discuss the implementation of the graphical user interface subsystem and the implementation of image acquisition subsystem using microcontroller Arduino. Graphical user interface system is developed using Nikon software development kit (SDK) which can be accessed through digiCamControl application program interface (API). Image acquisition protocol will also be developed using Nikon SDK with the help of media transfer protocol (MTP). Result of the implementation is a windows application as GUI and communication system to to connect GUI and Arduino. <br /> <br /> Both of these subsystems will help photographer in producing an array of images with the same frame but different focus fields. The output of these systems will be used as inputs to image fusion (focus stacking) subsystem.
