To get back on track; a photo taken with the exposure decided by starting with sunny 16 and adjusting it slightly.
A Zorki (-1) and Industart-22 lens and probably Kodak VR.

PS Part of a sequence of photos showing an empty truck and ending with the loco on it and driving out of the car park. Turning the truck round in a car park had to be seen to be believed. See them here:-

Hi David and all,
I have had a long time interest in meters and have quite a few.
The interesting thing to me as a scientist, is how long it took to standardise film speed.
We had Scheiner, Weston,ASA, DIN and now ISO, not to mention the Russian GOST and so many others.
In science we have been metric forever and I despair of countries that are not.
I worked in Labs in USA and London and had to be multi lingual.
Light meters are wonderful.
I had a friend in London who was chief engineer for Weston and I asked once how they made money out of light meters.
You know those street lights that come on automatically?
We make the meters to do that.
Photo meters were just a sideline.
Useful for low light at the cricket too.
I have sold Lunasix s for that as they have a Lux value on the back.
Game over not enough light.
Cheers
Philip Sydney

Hi,
I guess the answer is that they didn't need it when film could be watched in the dark room and pulled out at the right moment; or as near to right as possible. And I guess pride came into it as everyone had their own method. That would have been knocked on the head by panchromatic film.
Add in the well known OMG reaction to anything scientific and there's the answer. Covid gives a lot of examples of that; my wife's a long retired biologist and I see her fuming at the politicians on TV and the nonsense they speak...
And I often wonder when dry plates and eventually film became commercially available and people stopped making their own plates. Then I guessed there would be a point to it.
And then as soon as H & D had started people disagreed; I've a 1937 and 1938 set of magazines in which the letters rumble on about how good H & D* was with Kodak and others disagreeing and Kodak suggesting they were working on it with what they did becoming ASA and then ISO etc.
Do you know the little German rhyme they used instead of Sunny-16? It goes "Sonne lacht - Blende acht" or when the sun laughs (smiles as we'd say) use f/8 as my interpretation.
Regards, David
* My quote about an H&D version of sunny 16 (in another thread) came from a quote from a 1920 RPS publication that was mentioned in the row.
