I am about providing a service to maximize the enjoyment and functionality of my clients' systems. That often has a lot to do with "getting it right" and sometimes nothing at all. When a client is educated on the relationship between their preferences and what calibration can provide, he can make an intelligent decision. Some people just want you to tell them what is right and calibrate their set and they will never care any more than that. Most people who come here are trying to get a better idea of what that means, and unfortunately, Michael, you and others often talk in circles rather than saying much that is useful.
Saying that calibration is not about getting an image that you like is like saying science is not about technology. It may well be so, but one must have an understanding of science to apply it properly. Similarly, if we have no regard for what makes a pleasing display, what point is there in what we do? You can be technically very correct and be useless at the same time. The relationship between the client's needs, the technology, and the ability to calibrate the system is the very crux of what we should be attending to. This is what separates the best calibrators from the fast food calibrators and the techno-snobs. To dichotomize calibration and preference makes the same mistake as the engineer who designs a product with no regard for how it will be applied in the real world. Arrogance at its worst...
You and I both know that you can contribute much more to the forums than this. Please do so.
I think this is kind of a straw argument. Michael's point is that calibration is about accuracy to an objective standard. Achieving that is an activity of mainly objective measurements, but done through experience. Inevitably, the display is not perfect, and some compromises will be made in achieving as accurate an image as possible.
But it isn't fundamentally about turning the adjustment knobs (or pressing buttons, unless you're stuck in the 80s like me!) to give you the picture that you like or that looks good to you.
But in dealing with a novice, you have to get across that fundamentally there isn't much in the way of preference when it comes to calibration, because it is about accuracy to a reference. It is kind of a black or white issue, in a crude sense, because either the image is accurate or it isn't.
Now, as you delve deeper, you realize that in achieving that accuracy, some compromises are necessary. These come into play when you decide what TV you want (what set of strengths and weaknesses of capabilities you end up with), and to a certain degree some other calibration choices (display brightness, gamma, perhaps black level w/ambient light, clip or don't clip peak whites, etc) can enter in. These are relatively advanced minutia.
But calibration, fundamentally, is about what the picture should
look like, not what some arbitrary person wants
the picture to look like. To this end, a big part of the calibration process is educating the customer, so that they learn to appreciate what an accurate image looks like. In this way, the person's wants begin to align with what is right, and then there isn't conflict. It is usually the person who has never gotten the chance to really appreciate an accurate reference image, and doesn't even know that they want that, and at first they may not want it.
It's like somebody who hears a really flat subwoofer, properly calibrated into the system for the first time. That's accurate. But to the unknowing ear, it might sound thin compared to the bad-sounding bloat of a crummy system with the bass set way too high. But then you spend some time listening and discussing what sounds "real," and suddenly somebody who wanted horribly inaccurate before simply out of lack of knowledge and attention, desires and appreciates accurate.
