Very interesting. Thanks for the link

I've still got an analog exposure calculator of sorts. Mine is in the form of a slide rule and is used for night exposures. It was printed in Popular Photography back in the sixties. The idea was you cut it out and glued it to thin cardboard to make your own slide rule.

There's scene descriptions printed on the back, each with a number from 1 to 26. When you match the scene number with film speed it give a series of shutter speeds and f stops for correct exposure.

The thing is called The Jiffy Calculator For Night-Light Exposure and shows a 1964 copyright by S.P. Martin. Certainly not as fancy as the one above but seemed close enough the few times I used it.

The level of complexity added by the option of changing film speed is unnecessary. All that is needed is a list of situations and the suggested exposure for 400 speed film, which is the speed most likely to be used. If 800 or 1600 or... Is used, a mental recalculation is easy.

But it is a cool instrument.

400 the most likely speed for a 1920 light meter? Guess again. Plus, that thing is really cool, why be such a negative nancy?

According to a quick Google, likely modern-equivalent film speeds after the First World War were up to around 50/18. Not totally speedy!

That thing is beautiful! I want one, however, I'd need one that used modern film speed, faster apertures and shutter speeds as well. And in English, but keeps the fancy script. And I think a mood slider should have a range from happy, light pics to brooding shadowy ones. Very cool, and thanks for posting this Adam!

Amazing device!

Makes my Johnson Exposure Calculator look simple!

Then, there's Andy's Handy.

About as far as an analog computer was taken in practical use.

I'm still trying to figure out what an analog camera is.

Cool device, very Lemony Snicket-ish
