Get close to 25 Stop of Dynamic Range with the RED Camera.
Here is a little trick. My friend and colleague writer/Director Christopher Glans at “Constant Production” just came up with a neat trick to get almost 25 Stop Dynamic range on a RED camera. Here is how he explains how it´s done and futher down you can watch some test footage.
“Some filmstuff – A small test for HDR shoots. I’ve been developing a technique to enable shooting in nearly 25 stops of dynamic range (the span between darkest shadows to brightest highlights) without getting the usual motion artifacts with Red HDRx. As a reference, no other camera on the market is able to achieve this dynamic range, which is far more than any existing screen could possibly show. But it enables powerful post production possibilities for those who need it.
You shoot 50 fps as the timebase with HDRx enabled (on Weapon MG that’s only possible at 5K 2:1 cause the effective exposure rate ends up at 100 fps, two exposures 50 times a sec).Then in post, put that 50 fps footage into a 25 fps timeline, edit, grade and apply digital motion blur. Previously such motion blur wouldn’t do much to reduce the artifacts you get because of two exposures, but because 50 fps uses these exposures closer to each other in time, there’s less difference between the two, making the motion blur blend them much better. In the end you get footage that looks much more like traditional footage, but with 25 stops of DR
Have a great Friday and weekend!!!
