What ISO were HCB's eyes calibrated for? I take these anecdotes with a grain of salt. The eye/brain combo compensates. The notion that the brain can deduce EV using the eyes, is a source of skepticism for me.

I'd be interested in performing a similar experiment with my meter and someone that claims they can do what HCB claimed he could do. I'm not going to argue over anecdotes and I'm not going to call anyone a liar. I'm a skeptic and I would enjoy being proven wrong through empirical, rather than anecdotal evidence, that's all.
P.S. I am almost motivated to sell all my Nikon equipment and buy a Leica M6 or M7 with a couple of lenses in the hopes of minimalizing and focusing on image making instead of equipment fussing!
OK, Next sunny day take your meter and meter an outdoor average frontlit scene or meter the cloudless northern sky 45 degrees up. I'd wager you'll get 1/ISO @ f/16 +/- half-stop. The "sunny-16 rule" y'know? Should hold in Kansas though maybe a bit different in Colorado.
For years people without meters have used exposure tables printed in film boxes, photoguides, and more recently on the internet to estimate proper exposure. It's simply a matter of perceiving the difference between a sunny and overcast day, distinct vs. soft shadows, a bright room vs. a dim one, the edge of a forest or the deep shade within, etc.
St. Ansel also reports he used this sort of experiential "guess" based on his learned experience of the luminance of the full moon in his famous Moonrise, Hernadez New Mexico image.
You can prove this "argument" to yourself easily if you take the time to attend to the situations you normally photograph in.
It's very weird but since I started doing wetplate I find I'm usually very close on initial exposures even though they may run into the tens of seconds. Another anecdote, but myself and other wetheads also report being able to almost physically feel the exposures needed as the exposure is in progress. You sense enough light has hit the plate sometimes sooner or in excess of the original guesstimate.
If only I could effectively apply this sense to the lottery... :rolleyes:
Seems to me you'd be a bit hypocritical having a built in meter.
Those times preceeded the great SLR revolution which was to be brought about by the Nikkon F, otherwise you'd see more F's in use.
Learning exposure via the Sunny 16 and experience route is a learned talent that is not all that difficult. And keep in mind that many of those images spent long hours in the darkroom with a dodge or burn tool or other printing technique.
There is nothing new under the sun.

1/ISO? like 1/100 for ISO 100, 1/400 for ISO 400?
