'Transformers' to pump up 3D brightness

Source: Variety.com

quote:
Complaints about dim 3D projection and worries about how to "save 3D" are finally prompting action -- from one studio, anyway.
For "Transformers: Dark of the Moon," Paramount and Michael Bay have gone beyond simply asking exhibs to turn their lamps up to proper brightness. Par is taking the unprecedented step of releasing a special digital print aimed at delivering almost twice the brightness of standard 3D projection -- even more than the dual-projector Imax Digital theaters.

By releasing the enhanced digital prints, which have been mastered and color graded for the extra brightness, Par is pushing the 3D envelope even farther than James Cameron and Fox did on "We want the best presentation possible," said helmer Michael Bay in an email to Variety. "We have created a special version with extra sharpening, color and contrast. It is a superior look in the format. The brighter the image, the brain processes in a different way (sic) and the result sharpens and makes it more vibrant.

"We did many studies on the formats for presentation and I found this to be the best result."

The special brighter digital prints will go to about 2,000 theaters, all using the RealD 3D system. Remaining screens, including all RealD competitors, will run at standard brightness.

It's unclear whether exhibs will advertise the special extra-bright 3D screens. AMC Theaters confirmed they will show the enhanced package but declined further comment. Exhibs may want to avoid planting the notion that some 3D screens are better than others when there's no price distinction between the screens.

No previous pic has been released with multiple 3D digital prints for different levels of brightness.

Standard brightness for a 2D digital cinema system is 14 Foot Lamberts, measured off the screen. About 75%-90% of the light is lost in 3D, so the informal standard for 3D systems is 3.5 FL, measured through the glasses. That's the light level 3D pics are color graded for.

However, some theaters either dim their lamps to save money or don't change them often, and therefore show pictures below standard brightness. That gloom, which prompted grumbling from cinephiles for regular 2D, has generated significant pushback over 3D.

The special DCPs for "Transformers 3" have been graded for 6 FL, amost twice the brightness of the usual 3D standard. By comparison, the dual-projector Imax Digital system only averages 5.5 FL for 3D.

"We believe in delivering premium 3D, so we applaud Paramount Pictures and Michael Bay for their focus on quality and presenting the brightest, most immersive and ultra realistic 3D entertainment experience possible," said a rep for Real D. "RealD 3D projection technology delivers twice the light of other 3D systems, making it possible to present an optimized 3D presentation like this on screens of all sizes."

No studio has sent out multiple DCPs for different 3D light levels for general release. According to Fox post VP Steve Barnett, for the "Avatar" premieres Cameron wanted extra brightness and dynamic range, so he did a special DCP graded and color corrected for 10 FL, but that required two projectors.

"Jim wanted it to be the best dream he could have for 3D color and projection," Barnett said. "That shows the real stunning possibilities for what 3D can be. It's why directors of photography would like a higher light level for 3D. That's why we're hoping that laser light engines will get that light level up for 3D."

However, for general release, "Avatar" only was graded for the de facto standard of 3.5 FL. Fox sent out multiple DCPs of "Avatar" for different screen formats (1.85 and 2.35) and to acommodate "ghostbusted" and "non-ghostbusted" 3D projectors.

Barnett expects the new laser light engines to get 3D light levels up to 7-10 FL. The special "Transformers" package approaches that level.

I'm gathering this is going to be over at the Uptown theater here in DC - I hope it looks as bright as this article suggests, the darkness of Pirates 4 really hampered the 3D effects considerably.

Since when was the "defacto" standard 3.5? the range since day-1 was 3.0-5.0. Disney, in particlar calls for 4.5fL +/- 1fL (still allowing for a bottom end of 3.5fL but also notably pushing it higher to 5.5fL (just .5fL from the uber-bright 6.0fL Transformers).

As as some of you might have read in my other postings, it is not so cut an dried as this article makes it out. If the print is color timed for 6.0fL...in what part of the screen? The middle? Because on Real-D, that will be the only part that is 6.0 unless the screen has a notable curve to it.

In truth, a Dolby or XpanD running at 5.0fL on a lower gain screen is brighter (overall) than a Real-D (or MasterImage) running 6fL on a flat silver screen.

If they've figured out a way to make the 3-D look better, why in the world wouldn't they do that to all 3-D digital prints??

running 6fL on a flat silver screen
is that because the silver screen eats up so much light?

Ya, I got the notice of the "Platinum Edition" - being a brighter 3D version of "TR3:Moon" - and I can run the regular version if needed. Like 'wow! are we impressed.'

It isn't that a silver screen eats or gets you light. It is that it distributes it so awfully.

This picture shows the problem in a nut shell. Note, this picture was taken with a flash so the problem is exaggerated due to the flash (I have pictures with JUST the projected white light but they are not ready yet for posting). The picture is not re-touched in any way other than converted from a RAW file to a JPEG (and sized to 550 pixels horz. as per forum requirements).

You can tell exactly where I was standing relative to the screen just by the location of the hot-spot. Since the screen has a slight curve (and the flash has more horizontal distribution of light) the spot is elongated horizontally.

What this shows, however, is that when one sets their center illumination level to 5.0fl or 6.0fL...it is only 6.0fL at ONE point on the screen and just for the center seat in the auditorium (if the installer was following SMPTE/DCI specs). The average light will NOT be 6.0fL. It will actually be about 3.5-3.6...which based on the article, may have been their goal. The corner brightness will be around 2fL. The sides will be just under 3fL. Compare that to a Matte-White screen or a notably lower gain set to just 5.0fL. Its average would be about 4.7fL or about 30% brighter appearing than the silver screen setting at 6.0fL. A 1.3 gain screen set to 5.0fL has an average illumination of about 4.3fL which is still 23% brighter than the silver screen at 6.0.

Now, as you curve the screen you can close these numbers way down...but the image will have geometric issues and there will be cropping of the center of the image since scaling is so frowned upon (and nobody is making curve field corrected DCinema lenses at this time).

Wow. 6fL over 4.5 (how did they makeup the 3.5? Just to enable the 'Twice as bright' myth?). Now we all will be 'blinded by the light'.

First of all these journalists should learn about the difference between 'mastering for x fL' and 'projecting at x fL'.

This is just a PR joke to instrumentalize the recent 'Sony 3D/2D is too dark' debacle. They must be really scared of the box office for T-3...

And it is clearly against DCI specs:

'2.1. Single Inventory of Stereoscopic Digital Cinema Packages
(DCP)
A single stereoscopic DCP shall be able to be used for all stereoscopic implementations (e.g., no stereoscopic exhibition system shall require a unique color or density timing). It is not required or intended that the same image track file used for stereoscopic DCPs also be used for nonstereoscopic
DCPs.
Additionally, no signal pre-processing unique to any single stereoscopic exhibition technology shall be required of a stereoscopic Digital Cinema Distribution Master (DCDM) or DCP.'

That's why they got rid of the GhostBusted DCPs 2 years ago and implemented RealD 3D EQ server side.
Now RealD is back on that train to goof on the competition. Well, that other Bay movie will earn what it deserves anyway.
