Filters just don't work that well on many displays, often suggesting settings that are just plain wrong and/or too high.
In other words, a full calibration is one that is as close to a (good) professional calibration as possible and while there may be no exact definition, it certainly involves a lot more than tweaking basic settings and chosing the right presets and options. I'm not discrediting doing the latter, but I can honestly say there is much more to a calibration than that.
There can be but there doesn't have to be. Blue filters, for instance, can in many cases be just as accurate and precise as a blue-only mode, and is far simpler than trying to measure the luminances and chromaticities of all the primaries and white and setting color saturation via this method which is fairly advanced even for hard-core enthusiasts. The weaknesses of the filter method are a little exaggerated, and as long as you test the filter first you can easily compensate a couple clicks and come pretty damn exactingly close. And again, in many cases using a filter is just as precise as a blue-only mode and it is very simple to test the efficacy of the filter.
Keep in mind that for a long time professional calibrators might only have been equipped with optical comparators. We have advanced a lot since then, hardware has grown much better and much cheaper and has brought many things down to the realm of affordability not just for professionals, but for occassional calibrators and now even enthusiasts here at AVS looking to DIY. This is fantastic, but doing a basic calibration from just a test disc is still the largest single benefit you can get on your display and the best value by far, and it is still a form of display calibration. Is it taking things to 11? No. But then there are many people with older TVs or who cannot afford to spend several hundred dollars to have someone calibrate their display, let alone the hundreds or thousands to acquire colorimetry hardware/software themselves. And as we have suggested here on this forum for many many years, the best place for a beginner enthusiast to start is to buy a simple test disc, or even download the free AVS AVCHD disc, and adjust their display's basic settings. You can achieve a surprisingly great image this way, and it is a basic calibration. Basic? Yes. But still very effective and a fantastic value.
I would love it if every person would value and could afford to spend several hundred dollars on the very best calibration possible, but not everyone can afford that.
It would be a great shame if this forum changed to a place where the beginner enthusiast would be discouraged from learning from the beginning: the basics simply because some would dismiss it as somehow NOT related to calibration.
I am here to spread the love of high quality, accurate images, and to help other people achieve that by sharing knowledge and experience and also by learning from others here who are more knowledgeable than I. We were all
beginners at some point. Never forget that simple fact. I want to encourage novices to do what they can within their means and knowledge. It's enjoyable, and it yields great results. If they then decide they want to take it to the next level, maybe they hire a pro, or maybe they really are hobbyists and acquire hardware of their own. Either way my aim is encouragement, not dismissing people for being beginners and chiding them for doing something that somehow isn't calibration when it certainly is part of calibration. We all start at the beginning.
