THE DYNAMIC HDR OPTIMIZER

Real time HDR to SRD conversion
optimizing luma and chroma to the
perception of the human eye.

ORIGINAL

Background is bright and
overexposed!

Reporter in the foreground
is too dark!

ARTIFICIAL LIGHT

Exposure improves!

Reporter suffers!

Make-up necessary!

LUMAGIC

No artificial light necessary!

Over- and underexposed areas
are corrected in real time!

No more burnt out areas in the picture!

LUMAGIC USED IN LIVE PRODUCTION

The video shows the difference between static and local dynamic conversion of a high dynamic scene. LUMAGIC provides more than simply better image quality, it also affects the way in which content is produced.

By optimizing the lighting balance and exposure, aperture setting become less crucial. As long as the information in the captured scene is not absolutely crushed or burnt-out, LUMAGIC will map it into the optimal contrast for the human eye.

For sports in sun and shade

In outdoor sports such as soccer sudden changes from sun to shade can be a challenge: even if the camera team reacts quickly, the ball invariably will be briefly underexposed, colors will change. Not with Lumagic: luma and chroma will be auto-corrected in real time. And your viewers will love it.

For reporting in the field

A common situation in the field: the background in the sun is bright-lit and overexposed while the reporter in the foreground appears too dark. Add a fully equipped production lighting team: the footage improves somewhat but the reporter suffers. The glaring light makes him squint and adds to the heat. A few minutes into the shot, new make-up is required. With Lumagic you can leave the lighting team and all that equipment at home. Fully automatically overexposed and underexposed sections are corrected. A perfect shot, faster and cheaper.

For efficient studio production

Looking for savings in a studio production environment? Maybe you can save some of those camera men. With Lumagic, there is no need to have a camera man in place just to adapt the exposure. Lumagic does it for you, automatically.

LUMAGIC
COMPARISON WITH DaVinci RESOLVE

In the video the LUMAGIC technology is compared with the color correction of the DaVinci Resolve software.

Benefit 1: Improve your native HDR

Use LUMAGIC to optimize your HDR before broadcasting it. Automatically, the footage will become more convincing, colours brighter, contrasts improved. The HDR is adapted to what the human eye can see.

Benefit 2: Use your HDR to create brilliant SDR footage

Still, only few consumers own one of those expensive HDR screens. But here comes the maybe biggest advantage of LUMAGIC: you can use the HDR to create amazingly brilliant SDR content. Let your SDR consumers participate in the HDR experience.

Benefit 3: Archive in SDR and reconstruct the HDR

Few broadcasters like to add another house format. But switching to HDR doesn’t necessarily mean switching to a HDR house format. You can “compress” nearly loss-less your HDR and archive this material. LUMAGIC’S patented algorithm is able to maintain almost the entire contrast range of the original HDR image when down-converting to SDR. When upconverting the SDR signal again, this becomes key for reconstructing the HDR image almost to its original contrast range.

Benefit 4: Reduce the need for aperture changes

Today, even with an agile camera man correct aperture changes can be a challenge, especially in sports, music, and other environments with fast changing light conditions. LUMAGIC, however, can react not only much faster (within a couple of frames) but also manage the luma on a sectional level. Hence, the camera man can focus on catching the right content and get those breath-taking shots.

Benefit 5: Work file-based or in the cloud

You can use LUMAGIC on premise or as a cloud solution.
