the HT consumers generally could care less about matching his various displays. He wants to see the colors as the artistic chain intends them to be seen and that is flawed.
W e sell the consumer on that though.
But it is all BS. The coordinates are based on a multiplier chosen for a defined standard viewer. Colorists (man) and HT consumers (many) do not have eyes meeting that definition.Unless one eye has been corrected with a new lens there really is no way of making a two eyes summed correction because there is no way of measuring the degree of filteration where both ares have yellow filters due to aging.
But I do feel that for many investing in equipment and programs to calibrations or even paying for a calibrator which essentially be almost a complete waste iof money. They will simply not get the objective they are seeking.
And the argument of calibrating to see it the same as you would see it in real life is specious. You have the error introduced by the colorist's eyes and the fact that viewing outdoors etc will ralely be under the same lighting conditions the film was shot. Its all BS.i
There has never been a man made system that hasn't been flawed. With all the enormous devotion of talent and funding to NASA over the decades, they still lost one capsule crew and two shuttle crews. There has also never been a time when a certain portion of video program professionals haven't argued and fought against the implementation of standards, engineering guidelines, and recommended practices published by industry standards bodies. It gets even worse in the consumer electronics portion of the video industry. Industry professionals can have all sorts of agendas, based upon a wide variety of motives. Standards bodies like SMPTE and the ITU are faced with a daunting challenge to unify and elevate the international motion imaging industry. THX faced similar opposition in their original mission to promote the observance of SMPTE standards and best practices in the film mastering and exhibition segments of the industry. Their task has to be reminiscent of the proverbial herding of cats. Genuine leaders and luminaries in the industry are tireless advocates of unity, consistency, reliability, quality, fidelity, and discovery. However, as with any field of endeavor, there will sometimes be loud voices that get attention, only to advance an ego, a misplaced sense of priority, or obsessive-compulsive cynicism, etc. There is room in any industry for disagreement and debate. How does any side of an argument elevate the subject, not just propose a contrary perspective?
Here's a testimony from an award winning expert from within the cinematography ranks that sheds light upon this discussion:
"2 April 2008
From Allen Daviau, ASC [ http://www.imdb.com/name/nm0005679/
]Today's cinematographers go to great lengths to insure that all of the richness, range, and detail of their original images reach the home screens of the viewers. Throughout the photo-chemical laboratory processes and the full range of digital manipulations, the cinematographer who cares wants to ensure that every step taken is in the best interest of the look of that motion picture.
This has been the case for some time, but with the real arrival of a High Definition television system and the subsequent enlargement of the home image size, the responsibility has a greater intensity. We, and all of the technicians who work with us, want you to feel all of the power of those images that so many people, in front of and behind the camera, fought to achieve.
I think that you would be very pleased with the intensity and precision of our efforts. In return, we make an important request of you. Please be very sure that your home viewing screen is capable of displaying all of the quality that has gone into the motion picture that you are viewing. You may own a very high quality system, but if it has not been properly calibrated, you would be shocked at how much you are missing.
Starting with the quality of your incoming signal, be it from an antenna, cable, satellite dish, or disc, it should be capable of delivering everything in the original master. The adjustment of your display device should be done to insure that it is accurate in terms of contrast, brightness, color temperature, and color intensity.
Unfortunately, the manner in which displays are adjusted at the factory is to ensure that it gets attention in a store, surrounded by many other screens. It has not been adjusted to display the qualities that the filmmakers considered important. If you have these adjustments made properly, your enjoyment of those images will greatly increase. You will be seeing what we intended you to see, and all of us, the creators and the audience, will be very much happier.
It is well worth your time to be certain of your investment
Electronic motion imaging excellence is a fairly complex subject. Discussion must include the behavior of the electrical signals, functions of the recording and delivery devices, and human factors. One great key to not getting misdirected in such discussions is to not lose sight of the fundamentals. It may be helpful for readers to review this link: 'Display Calibration: Root Fundamentals'
It should also be acknowledged that there are more parts of the body that deteriorate with age than just the eyes, and affect one's powers of perception. Eyes can be physically intact but the optical cortex in the brain can suffer diminished function or damage. The brain also can suffer from senility and Alzheimer's at surprisingly young ages. Memory, perception, cognitive reasoning, and comprehension start to suffer. Much depends on genetics, diet, and lifestyle. Case studies are not comprehensive or complete due to the many sufferers who go unrecognized and/or unreported.
