Yes, but that won't necessarily be what it's called. Whatever kind of processing it is, Sony may have a proprietary name for it.

Kris Deering · 03-04-2009, 08:16 PM

It will be some sort of dynamic contrast or dynamic range enhancement that you can turn off or at least turn down.

Jeff Kleist · 03-04-2009, 08:17 PM

or "black enhancement"

Yet another of the many superfluous circuits in modern consumer video systems which are named for the opposite effect of the one they produce.

In fact, any time you encounter any control with the term "enhancement" ascribed to it, you should probably run the other way.

What about breast enhancements?

I run as well. I prefer my women like my HD picture: natural (no DNR or edge enhancement).

I don't want females with more plastic in them than my PlayStation 3.

They're great until the clothes come off. Then-- UGH!

I second the preference for naturals! (except when they're below a certain level-- in which case a little "enhancement" is okay

)

I'm not sure - but you may be seeing the Sony W4100 series "sparkles" problem. If that is what you see - you can get a fix from sony. Search for Sony Sparkles on avsforum.com.

I'm the same way...I prefer a natural B+/C- cup.

"black enhancement"

I have a Sony Bravia XBR4 series TV. The television has a lot of different picture enhancement functions, but I can't find anything labeled "black enhancement."

120Hz Motion Enhancer? I leave it deactivated almost always. The only time I'm tempted to use that interpolation thingie is during a live, shot on video sports broadcast. It looks terrible when applied to a Blu-ray movie. The filter yields an effect similar to a broadcast videotape pushed into fast-forward mode. Not natural looking at all.

I leave my TV's "sharpness" setting set at "Minimum" and Edge Enhancer set at "off." Blu-ray movies look much better and more natural that way.

Of course 4096x2160 is called 4K (not 8K). I should have said 4K rather than 8K. So there is no need to go for 8K to accurately reproduce a 2K image. 4k would do. (Thanks for the correction. If I can I will edit my previous post.)

And if your image contains 2 pictures of chessboards, one perfectly aligned with the 2k pixels, and one half a pixel misaligned, there would be no way to reproduce both of them correctly by shifting the image, no matter how high a resolution you capture at before downsampling.
.....

When down sampled from 4K to 2K, the original 4K scan or capture has complete information to reproduce at 2K. If it is scanned at 2K the information is lost at the time of scan, so it cannot be accurately reproduce at 2K. Once scanned or captured at 4K, I expect, depending on the downsampling algorithm a better (or more accurate) image can be reproduced at 2K.

Take the chessboard pattern as an example. If the image is captured with 2K resolution and if the capture pixel grid is 1/2 pixel out on both axis, it will not capture the grid. However, if it is captured or scanned at 4K and if downsampling based on dropping alternate columns and rows is applied, the original pattern can be reproduced.

And no, I’m not talking about Inception, as that’s only in production. If you want to know about that sci-fi action film, Wally may break down and leak something this afternoon in Universal City but, I say only might.

I’m talking about………….
http://www.bigpicturebigsound.com/Ex...dventure.shtml

Would anyone care to venture as to how high of a resolution scan (in “k”) it would take to capture all the details of picture information on a single frame of negative recorded in IMAX format?......hint, it isn’t 8k despite the fact that current technology/practical storage limits us to this.
Another hint…..it’s the same rez as the contact prints that were made from the IMAX negatives of a feature film that some people here may have already seen on Blu-ray.

Keep in mind, that the image area of an IMAX film is larger than that of ‘traditional’ 65 mm OCN. Somebody else can look it up and list the exact mm. in width and height comparison for you folks to help with your guesses.

As an aside, one of the ordeals involved in making this motion picture was that Shaun MacGillivary (son of Laguna Beach

filmmaker Greg MacGillivray), had to haul a 300 lb. IMAX Solido 3D camera down and up a 600 ft. trail…..along with 7 other guys that traded turns in the heavy lifting/carrying chores. Another pecularity is that due to the remote location (the bottom of the canyon) they had no ‘dailies’ in the true sense of the word.

The good news………despite rigging the camera on the very bow of the raft while it went through a few of the biggest rapids on the Colorado River………the camera survived.

Wally, are you listenting?

Something to keep in mind before answering this question is the difference between the "k" term and the "MP" term.

Doctorossi · 03-05-2009, 03:29 PM

5.6k.

According to John Galt at Panavision, carefully exposed IMAX peaks at just under 3k horizontal (limited by the lens optics), so, considering Nyquist, a 6k scan should accomplish it in any practical applications.

Very smart man.

However, if you want to quote somebody, why not quote the person in the U.S. that has scanned more IMAX material than anyone else on earth.
