- Extensive Database:
Light Source’s primary function is to get you close to the exposure you wish to operate in, whether in F/T stops or foot-candles.
The T/F Stop exposure levels outputted by the calculator would be correct for the center of the lit area, falling to approximately 50% exposure at each side of the beam spread.
The database has been complied from manufacturer data to contain as much relevant information for each fixture taking into account specifics for lens type, lamp setting and specific beam spread.
Light Source updates will include new lamps and manufacturers as they come on board.
Light Source has been built to be intuitive and quick to use while in the middle of a job. Anyone with a basic understanding of light / photography can pick it up quickly and get great results fast.
Excellent App !! – but please go metric………….
Thanks Per, The current version does allow you to choose either feet or metres in the settings page.
I have just referred you terrific app Light Source Pro to industry professional cinematographers globally on the Cinematography forum on LinkedIn after one member from the UK was asking for any advice on apps that performs his needs, and Light Source Pro does just that.
Thanks for a truly great app, although I am using the free version (non pro) its a thorough and accurate tool, you guys went to alot of research and time to assemble this, well done
