I just 'down-loaded' this great exposure calculating app from e-bay ;) :

Despite being around 90 years old, it fits snugly in the palm just like an iPhone. Samsung should have brought one along to their court case with Apple, who obviously stole the iPhone form-factor from Pathe..

The six different sliders along the edges all combine via a complex series of interlocking levers to output an aperture f-stop. Anything below f/3.5 gives a reading of "insufficient light", which gives you an idea of the lens speeds available in the day. There's also no provision for film stock speed, since only one speed was available. It still works though, which after 90 years is more than you could hope for from your iPhone. B)

Exactly the kind of things that make a cinematographer’s life worth living, at least mine

Thank you so much for posting!
