The Filmcalculator is a program for Film professionals. Usefull for DOP’s, focuspullers, clapperloaders, VFX supervisors, still photographers but also location managers, art directors etc.
It is a great tool to be used during prep, shoot and post-production. Its made by crew members and has a 15 year history of being used on PDAs. There are over 32 calculations and info screens possible for three different disciplines:

Film, Digital and Photography.

The interface is made to be quick and simple. No fancy graphics but to the point input and results. No searching on the screen but a clear overview.

The program is actively maintained for all those years and still expanding.
Film stock, Lens, Lamp and Camera database are kept up to date using a central remote server for quick updates without the need to update the program.

Contact us if you miss something and we will try to add it. We even did this once overnight for a focuspuller.
