Re: A few words about...™ Patton -- in Blu-Ray
By High Frequency Information (HFI) I'm referring to a part of the image which would contain minute detail information...
Information which reproduces not only on Blu, but on SD.
Stubble on an actor's face, along with facial details such as tiny scars or marks seen in close-ups -- look at the worst of it and skin becomes "plastic" as in The Untouchables. Patton has this problem. Flesh has imperfections, even if heavily made up;
Detail in hair;
Detail on the walls of buildings, which when DNR'd looks smooth; Look at an exterior wall, be it stucco or brick and you'll see heavy detail. Look at the buildings in Patton and there is nothing.
Grass, and not just a mass of green, but the ability via BD to differentiate;
Trees, and not just trees, but the leaves moving, rather than being mass of green;
In Patton...
Dirt on a Mercedes staff car, a Jeep or a motorcycle; not just an overlay of beige dirty color -- DIRT!
Blu-Ray allows this.
Leather that isn't simply shiny black, but shows imperfections, grain and wear;
And lastly, background information that isn't simply a mass of color.
The point here is that the Blu-Ray process has the capacity and the ability to reproduce fine detail magnificently.
Remove grain incorrectly, or use the wrong process, and you lose every bit of detail that has been captured within those bits of grain, and things become, well...
pretty and clean...
and not only totally non-representative of film.
But no longer representative of the work that some might attempt to replicate.
This isn't simply about grain, which DONE PROPERLY as I've explained, can be totally removed without losing a single bit of detail, or lowered to replicate any film stock ever produced. Had Warner wanted their high def of Bullitt to look like it had been shot on early '90s 5247 rather than late '60s 5254, they could have done it. They chose not to, and the proper -- original -- look of Bullitt is there in high definition.
This is about making something look clean and wrong concurrently.
This is something exceedingly easy to do correctly.
Two appended final points:
1. This cannot be seen in screen grabs.
2. On smaller screens, for example anything under around 35", this is almost moot, as the image with or without heavily applied DNR will look very similar unless one knows what they are looking for. On my 30" Sony HD CRT, Patton looked fabulous.
And this presents yet another problem. If someone is working on a project and using a smaller professional monitor as opposed to viewing on a large screen, they may not see the damage that is being done.
