...photographers somehow think that digital technology is superior. For example, people think a dry cabinet with a digital hygrometer is somehow more accurate and better than one with a non-digital hygrometer. And they'll pay more for the fomer!
The truth? The measuring instrument (ie the part that senses the air humidity) is a mechanical, analog device! There's some kind of circuit to convert the reading to digital, but the digital reading is only as accurate as the analog sensor to start with.
So why pay more for a digital dry cabinet when it costs more to purchase and operate (battery cost)? Your analog meter needs no power, and if calibrated, is just as accurate!
Beats me.
Same applies for many other things-- bathroom scales, thermometers, light meters, etc.
Digital costs more, eats batteries, and has no advantage-- yet people somehow think digital is superior.
