TimeLapse Calculator PRO – an auxiliary application that will become an assistant for photographers who decide to create a timelapse. But they do not yet have enough experience or do not know certain parameters in order to get the perfect result. This program, having only a few parameters, calculates the missing data. Given that users will be able to get the desired sequence of frames. The interval, duration, duration, and everything else can be both used and found out using the calculator. The project is definitely worth testing for anyone who is interested in serial shooting of events.
