the level of continued ignorance can be really entertaining... ;-)))) hahahaaaaaa
do we need
a 3D LUT ? No.
do we need
a 6pt cal ? No.
but the best possible calibration is a 3D LUT and there are VISIBLE differences compared to a 6pt cal ON THE VT60
, ergo improvements in IQ........ FYI: IMAGE QUALITY
and no, u can see < dE 3 in some color regions, also been stated and visually demonstrated a million times...
whether one spends (or can afford to spend) the extra money on 3D LUT equipment, or on a cal sw, or on a spectro, or on a meter in general that is whole different different story and has nothing to with what the best calibration is... the "jealousy" factor in the typical posts "yeah, I can't afford it and it doesn't really do anything anyways although I've never tested it" is very, very scientific
and really helpful to other people coming here looking for OPTIONS
... if and when they jump into 3D LUTs is up to them...
and another thing that has been stated now a gazillion times and one thing SillySally mentioned in his last posts: you can only know what you validate
, ergo the information peeps in here argue with their 6pt cals comes from verifying at best
100 points out of a 16.7 million points color gamut... some of the posts here include 10pt
the minimum to run is 1000 and while that is 10 times more information, it is still only a start... and once u run a 1000 pt validation patch set u will now see all the points dE > 3....
just image u'd validate the whole gamut.... OH BOY !
besides the much higher accuracy due to the sheer amount of correction points, a 3D LUT can fix/improve complex greyscale issues
, gamma issues
, specific color regions etc etc etc..... FYI: skin tones, blue skies etc...
although I'm not too much of a fan of HTPC (on a budget it's a great solution), the whole Argyll madVR combo (once u get it working, which can be annoying and very time consuming) is a free option
to check out/experience 3D LUTs... and then u could at least somewhat make an "informed decision" to decide whether to spend money on real equipment for your signal pipeline (--> your HT setup)...
pause the movie on any frame, enable/disable the 3D LUT... if ur eyes see only the tiniest of image shift, that means thousands and thousands of pixels (--> colors) are being corrected... 24 times per second... and if u're "lucky" on some frames u will see quite a drastic image shift which means hundreds of thousands / millions of pixels are corrected...
what all the "calibrators" don't do (and don't have time to do) is to check for (and show the customer) these "drastic frames" which will be specific to your set... there are special patterns and validation footage u can use, but then again, it could be a random shot in a western with blue sky and yellowish/earth tones in the same frame
that would display a drastic improvement on a particular TV set...
so no, u don't have
to get a 3D LUT, but it is the best possible calibration. That is the reason why US$40,000+ Pro screens that are ultra linear are also corrected and calibrated with a 3D LUT.
watched NOAH yesterday on Blu-ray on one of my 65^3 cal'ed VT60s.... looked outstanding.
