I'm looking for a non-CGI movie with very good and accurate picture quality. Any suggestions?

You'll probably get lots of recommendations but my first choice is Seabiscuit.

'Baraka' is a good choice. However, full motion content is not nearly as revealing, or time saving, as purpose-built still frame test patterns.

Thanks, I've used test patterns already. I have a Panasonic 60UT50. A couple guys have posted their calibrated WB settings in the UT settings thread. They have the 50 inch version and I understand that all TVs need to be calibrated individually to get a very accurate result. A number of people have posted that using the same clicks off of default have given them good results. I thought it was worth a shot, so I have since changed my white balance settings to the same relative settings as the calibrated TV. I'm hoping that all the UT50 TVs will have the same inherent WB issues and this should be getting me closer to reference.

Taking all this into consideration, my goal is to find a blu-ray that I know should be very life-like and use that as a reference. I'll watch the TV for a week with the "modified settings" and then go back to default and see which I think are more true to "reality". I'll put Baraka on my netflix cue.

+1 on that for sure. But I find Pride and Prejudice to be even more stunning. But I have the HD-DVD version so I don't know what the Blu-ray version is like. I would think it would be similarly gorgeous.

From Wikipedia's article on 'Baraka:'

"Following previous DVD releases, in 2007 the original 65 mm negative was re-scanned at 8K (a horizontal resolution of 8192 pixels) with equipment designed specifically for Baraka at FotoKem Laboratories. The automated 8K film scanner, operating continuously, took more than three weeks to finish scanning more than 150,000 frames (taking approximately 12–13 seconds to scan each frame), producing over 30 terabytes of image data in total. After a 16-month digital intermediate process, including a 96 kHz/24 bit audio remaster by Stearns for the DTS-HD Master Audio soundtrack of the film, the result was re-released on DVD and Blu-ray Disc in October 2008. Project supervisor Andrew Oran says this remastered Baraka is "arguably the highest quality DVD that's ever been made".[3] Chicago Sun-Times critic Roger Ebert describes the Blu-ray release as "the finest video disc I have ever viewed or ever imagined."[4]"

That’s a lot of talk, but Baraka had a very disappointing Blu-ray transfer—it was very over-sharpened and doesn’t look nearly as good as the better titles on the format. Even for the time it didn’t look too good.

It’s too bad, because the imagery of Baraka deserved better.

I haven't checked out Pride and Prejudice yet so that's another movie to certainly add to the list. I have a scene by scene list for Seabiscuit that points out what one should look for and why. It was put together by another poster and I have found it to be pretty good, as far as a movie goes, for checking all aspects of a calibration or adjustment. There are quite a few other blu-rays that are good for checking your settings as well.

Do you have a reference to that list? I'd be very interested. I'm trying to get shadow detail dialed in with a 21 pt gamma.

You can't do that without a meter and calibration software. You might THINK you can, but you can't. Everything you do without a meter is a guess. And any relatively decent movie will work as well as the next for trying to do something like this by eye... the reason is because every judgement you make about whether something is too bright or too dark is just a guess. Without metered readings you don't know if what you are seeing and settling on is reasonably accurate or not.

Human vision is EASY to fool and there are hundreds, possibly thousands of ways to fool it (look for optical illusions online for proof).

Doug is correct. Without meters and software, anything else is just a guess. It might be a good guess, but it is a guess none-the-less. But, for those who don't have the instrumentation, and would like something to use as a visual comparator, something like this is about as good as you're going to be able to do:

I know. I've got CalMAN Enthusiast with a C6 and a Lumagen and do auto 21 pt gamma and Color Cube calibration. The trouble I'm having is with the shadow detail below the 5% that the auto-cal gamma goes down to. The 5% stuff shows well but then it just becomes a black hole below that. I've tried moving that last 5% point down to .5% and manually bringing it up a little. Shadow detail improves dramatically and I still get good blacks (at least compared to the black bars on a 2.35 movie) but then the lower IRE scenes look flat... as expected I guess. This manual adjustment can't help but lower the gamma just above the correction. It's got to be made up somewhere.

I completely agree. The first time I saw a properly calibrated gamma (with my CalMAN package) was a "holy cr@p" moment for me. I had no idea what a difference just a good gamma would make.
