I gave reference as to where the info came from. You might not agree with what was offered, but why would you go so far as to label it misleading, when it comes from those who business is rooted in knowing such facts, not painting stuff like we both do? And suggesting that "I" edited in my conclusions? I'm shocked!!
Nope, I offered it up separate, right there....plain as day.

It's info I found interesting, and much of it has been discussed and held up as known and true fact on this very Forum, and by some whose interest was to discredit DIY efforts and their results. It all relates back to the validity of Screenies, ya know. Remember what was thrown about so often, that the CR seen in Screenies did not represent what the eye actually sees in person.
The stated facts above would seem to lend credence to that argument, at least the part where the Camera is concerned. But in a good "light" because the camera "might" be actually capturing CR levels we cannot perceive unless they are presented in "Static" form. (ie: Screen Shots) I
It also makes a case for the Contrast levels specs, and as actually seen on a Display to be as high as possible, so that one can get used to perceiving such. Also, controlled lighting environs will allow for optimal viewing of any degree of Contrast within an image.
I see what was stated as being factual, but overly disallowing the varied difference in People, and their ability to recognize differences when accustomed to them being of a certain level/property. All the different points between the lowest level of ambient light and the highest levels all place their own demands on the Contrast viewing situation. Some "Solutions" might handle a broad swath of various levels of AL, others working best within a certain confine of Hue & PJ.
I've seen, as I know you have as well, just how different the appearance of Contrast can be from one DIY application as compared to another. The Article points out that initially, the Human eye lags behind, but can adjust in a relatively short time to process higher CR levels. Certainly, that applies to what we are all looking to achieve here. Whites. Colors. Blacker 'Blacks'.
Brewed has a Panny AX100u. It has great CR specs and plenty of extra lumens. With a CR enhancing surface suited to his needs, he can assure himself of "perceiving" the very best Black levels he can. Gosh! He has a Dark Gray room, a PJ with high CR specs, Light Control, and a White primed wall. He wants the blacks within his projected image to look as dark as or darker than his walls do with the lights off/barely on.
Short of over utilizing his PJs BLE enhancement features to the point of crushing everything into oblivion, what would you suggest he do?
