It's not noise reduction. Read the article attached to that link here: http://www.dolby.com/entertainment-n...l-overview.pdf. It's actually dimmer control technology for LCDs utilising local rather than global backlight control.

Hence the winkie.

As another proviso, before claiming that a film has had its grain "digitally removed", make sure it wasn't shot digitally in the first place. ;)

I know he saw the "rainbows". I see them all the time, which is why I'm waiting for a reliable 3-element DLP projector. What I was saying is that before anyone comes on here and says "such-and-such a film is riddled with bad DVNR and EE", make sure the path between software and output device is...

It's truly sad how accurate your closing statement is. In the realm of psychology, this is how "backward masking" and subliminal messages were debunked. Because the individuals claiming that these phenomena "worked" were bound and determined to prove it, they would tell people what to listen for...

Doug: I, for one, appreciate your posts. They give us great insight into the perils of converting film into the digital realm. I have seen some really shoddy transfers and had often wondered, "What on earth were they thinking doing this?" Again, thanks.

300 was shot on film (Super 35, to be precise), but entirely against green screen and composited digitally with digitally rendered backgrounds.

Another question it raises is how much grain was added as a result of release prints being several generations away from the ONeg?

Doug, keep in mind that the 35mm print that David was referring to was an independent film. It probably looked as good as he described it because a limited number of prints were made, hardly the same thing as a massive 5-6,000 print run of the average Hollywood blockbuster. With smaller print...

Since the only other option is to build a 35mm screening room, rent prints and compare them with the HD transfers, you tell me.

Probably the easiest way to deal with the grain issue is to use a phrase like, "...which is consistent with the film's original theatrical presentation." I realise that unless reviewers get out to the movies regularly, they may not be able to claim this. Ah, the perils of being a HT enthusiast!

Or nearly any Super 35 production with an abundance of night scenes. Another one that comes to mind for the grain-haters is Saving Private Ryan.
