Joel. You know that on its face that is not my argument. That is your attempt to put my suggestion down and your argument does not measure up to international debate standards and hopefully you will not repeat it. If you can't come up with a legitimate argument just stop.
Calibration in pertinent part as it is presently defined is designed to make displays meet certain specified color standards. There are various tools for doing this and it is arquable which programs are best for studeo use. But for HT use, Spectracal and Chromapure are two of the best. Unfortunately, calibration does not involve adjustment for how one perceives color in light of their own eyes. In the process of color coding various eyes look at calibrated displays and code as to how they perceive the color rather than how its displayed and HT color calibration is designed just to duplicate the display. It is scientific, more or less repeatable, depends on your tolerance, I am running out of tolerance, and is based on international standards. It is interesting that you state you support uniform color reproduction over all color critical displays.
Now. Is a HT display a color critical display? Is it really.
Is it critical that that display match other displays.
Whether you like it or not, most HT customers want to see the colors as they were perceived by the artistic chain. This is critical. many HT viewers including most older ones say 60 and above will not see the colors as they were perceived by the artists. They will see color tinged grayscales and yellow tinged whites. Assuming they still posses a minimum of brain functionality, they will remember how white and gray used to look. They know they are seeing it not as the artists saw it even those the calibrator says the gray scales is perfectly gray. the calibrator as no tools by which to measure how the customer's eyes are off. If he did, he could compensate the display to let the customer see the colors the artistic chain saw assuming they had good eyes. But he can't. Calibration is for the display and not for what is perceived off the display.
Now. This is where your argument against my point fails so miserably. Calibration does not measure perception error There is no tool. Pity. It would be something else a calibration company could sell. You have no clue as to the degree of the error. No measurement tool.
Wait just a second. Has the light lit there yet? The customer has a tool. Now it may not be quantitative but it is qualitative. Yes the customer has eyes. The customer has a memory. The customer has a brain. Something a calibrator really doesn't need anymore. Autocal. OK OK I degress
The customer can see color tinging on a gray scale. Doesn't even involve his memory. The customer can tell me, gray is too blue or white is too yellow. He can say stop when it looks right to him. We can go back and repeat the stop point. It will likely be rather repeatable. Just depends on the tolerable degree of error.Sure the method is crude. But it is probably better than just living with the set error in perception that results from calibration and bad eyes. You can't measure it but the customer can with his eyes and by respomding to his perception can you say this has made matters worse for the customer. No you can't and don't insult me by trying. A qualitative measures is better than no measure. And the customer is made happy rather than just being told be happy, its right, its just you. Don't trivicize my suggestion. It brings me closer to the artistic intent than any calibration could. Deviation is good for deviates.
Surewly you can understand my point. And the need for deviation under appropriate circumstances. Its a good fix and far better than doing nothing.
