Eyeball Calibration...

You bring up an interesting point about problems with the use of the human eyeball as an objective instrument for measurement. I've been curious about it too. Last February during an eye exam I was able to prod the doctor into a color test. A nurse administered just a quick test. (Nothing too advanced when they're working with Medicare payment rates.) There is a slight color degradation, something I first learned in 1960 when I was twenty. No big deal, as far as I can see...

So, knock on wood, today it's no glaucoma or cataracts and an unaided vision of 20/30 in the 'instrument' I've been using to make these subjective measurement/observations.

I figure that if this measuring instrument 'sees' the same colors on the modern and vintage sets that were balanced using the 'instrument', the whole idea is a wash, because the sets were designed to be different. But in actuality, I have for example seen pale yellow 'look' the same on both sets. Then, in the same program, more saturated yellow areas are observed in different hues. So, could it be that, when I see the pallet of color in 'eyeball' agreement between the two sets, it becomes a 'reference' that confirms other differences in hue valid? I guess I'm going under that premise. Without a bevy of pricey instrumentation though, who knows if it holds water...?

I have fun messing with it.
