Oddly I thought of this when I saw the moon up last night, so I just wanted to throw this out there. The underlying "shade" really has no effect on what we consider "white", if you look at the moon at night it (at least to me) looks white (well white highlights do). However the "gain" of the moon is only 12% on average, this is actually less, than the "gain" of a standard gray card.
Not discounting your observations, but I think the explanation is likely one of Darin's.
Yeah, I'm sure it's just got to be some optical illusion or something. I really can't explain it. I'm sure in a total black room with no other colors or light sources to bias what I'm seeing or skew my perception of the colors, it would "look" normal...whatever normal is, LOL!
Darin has caused me to second guess everything I see with my own two eyes now...thanks bud!
No, but really Darin has allowed me to see past several obstacles and get a clearer grasp on the whole concept of color and lighting conditions. There's so many variable at play that have to be carefully matched in order to get the best out of your two-piece projection system. It's a lot of fun to me to learn and discuss all of these things though!
Like everyone says, I would need two identical black velvet rooms with the same equipment all calibrated exactly the same in order to perform proper A/B comparisons. And full screens, not samples. This would be awesome and I would totally do it if I had the $$$. Any investors out there, LOL?!
