There has been a lot of LT150 activity here lately. It's fun to see some excitement around...no matter what it's coming from. I like it.
I'm having some fun with the D-ILA Calibration Wizard, but it's not quite ready for prime time. I'm trying to get all of the parameters and coefficients working to my satisfaction.
There are some definite trade-offs, and I'm measuring to find out how to get the best solution. One of the trade-offs is black level vs. perfect flat gray scale. If you give up a bit of one, you can get quite a bit of the other. I had the G11 in "SC" range today (super contrast...greater than 1000:1), but had to let the gray scale go to h*ll on the bottom end to do it.
You can actually achieve over 1700:1 on the "G" series projectors without too much work, so remember that when someone starts quoting contrast numbers. There is much more to the story.
Anyway, in the end, those parameters might just end up "exposed" so you can set them however you wish. Reasonable defaults will be provided.
yeah, I come to this forum everyday and have not seen alot of dila posts/threat lately, but I guess everyone is enjoying their dila projectors now. I remember a year back where there used to be nothing but dila posts!, I missed those days. http://www.avsforum.com/ubb/smile.gif
wow!!!! super contrast 1000:1? I can't imaging our projectors having that much potential? great job!!!!
1000+:1 contrast ratio? Ye gods, Mark! Hell, can't you fix gray scale with a filter? If so, stick on a filter, get great contrast, pass image thru Panamorph to regain light loss from filter. Reasonable? Or just plain silly?
I like your idea of a few choices for the contrast/grey scale. Those of us with GreyHawk screen could probably give up a little contrast for better grey scale while those with a regular screens might want better contrast.
Also, since the wizard is so automated, one could try a medium approach then go slowly one way or the other to check how they liked the change. You could really fine tune your setup to get just the tradeoff you like.
Sorry to disappoint you, but the grayscale tradeoff was not color, but range. To get 1000:1 contrast, I crushed the blacks from 20 IRE down. No shadow detail at all, and the 1000:1 contrast was from 20 IRE to 100 IRE.
I really pushed the idea to see how far it goes and got 1723:1 on an unopened G11. Contrast isn't everything, though, and the loss of range was very apparent.
There will be a few options to configure, but mainly, I'm just ready to get this *out*! I've been working on it far too long.
