HDR Video a Reality
akaru writes "Using common DSLR cameras, some creative individuals have created an example of true HDR video. Instead of pseudo-HDR, they actually used multiple cameras and a beam splitter to record simultaneous video streams, and composited them together in post. Looks very intriguing."
I'm confused as to why, 18 seconds into the movie, they show a split screen with the darker half "overexposed" and the brighter half "underexposed". You'd figure the people who put this together wouldn't get it backwards like that, but evidently they did.
You already got some explainations. But it's just trying to fake a higher dynamic range of the camera.
If it was "good enough" already you would already get all details in dark and bright areas. But it's not. But it would had been better if it was and then you wouldn't need to do shit.
Now people take multiple exposures at various brightness levels and stitch them together trying to cover up all the dark and bright areas in one photo. The problem with both pictures and videos is that if anything moves while you're taking your exposures the stitched together image won't look that great ..
So they used two cameras and splitted the light inbetween them taking one exposure from each.
That it's video instead of pictures don't matter much, the problem would had been just the same if things moved in pictures.
