You had centerweighted TTL silicon photocell metering with LED
readouts in 1963? They had youngsters like you playing with that
stuff while I was delighted to get a Lunasix CdS meter even a couple
of years later??? :-)
Fortunately, my vintage 1999 camera (non-digital) of another make
still uses the same time-honoured method of exposure (factors
balanced: light value, reflectance value, film sensitivity, aperture,
transmission coefficients, exposure time) for which the details are
determined by test instruments and correlated/interpreted by organic
computer (self).
Hopefully all this will continue to function properly for a while.
Photography would be severely disappointing otherwise. ;-)
