Abstract Time-lapse is a photography technique that shoots frames of one scene at a certain interval and records the changing of the scene over the time. Time-lapse videos allow us to view process of time without having to wait for the actual duration. The Android operating system has a 59.65% share of the market, which makes it worthwhile to explore its application. Movements like Panning, Tilting and Sliding in time-lapse videos enhance the video presentation. The project is to develop an application combining both software (Android application) and hardware (Arduino program) to take time-lapse videos, and the bulb ramping technique is explored as well to take time-lapse frames in varying light conditions. The software application named LapseApp is featured with a new UI style compared to a previous project, white balance setting, zoom in and zoom out and video conversion. The hardware part contains Slider and Pan initialization, and Pan absolute position. A combination of time-lapse videos with panning, tilting, sliding and bulb-ramping were taken during the development of the project. Even though the videos are of good quality, some problems still can be observed like significant luminance change during bulb ramping. The main reason is that the intervals between exposure values are not small enough to deceive human eyes. The project was the development of a time-lapse photography application consisting of both software and hardware. Future work could focus on two areas: purchasing strong tilt and implementing absolute position to tilt head and, getting a camera with smaller intervals of exposures value to implement smoother bulb-ramping time-lapse video.
