The goal of this work was to create a fully automated synchronizer for macro photography, dedicated to water drop photography [2], [11]. An open-source electronics prototyping platform called Arduino was used for this purpose. The elaborated system includes a water system, a drop kit, and the synchronizer itself, attached to a digital photo camera. This system, named SyncBox, is simple, easy to use and fairly inexpensive. SyncBox can be operated using Dripper (the application interface) by a single mouse click, the pictures taken can be downloaded to a computer, and uploaded to the Internet. The proposed solution can be used as an interface for high-speed photography for water drop pictures, suitable for both amateur and professional purposes. The construction of the device, the interface, and exemplary pictures taken are shown in this paper. We conclude the paper with the proposed future works to make the entire system even more user friendly.
