Preface from the author: There is no real scientific setup to these tests, it’s purely a real-world sample of the practical application of HDRx vs under exposure with the Red Epic. It’s in no-way a perfect representation of the function, but more or less just one real-world case and how it can be used in some instances to reduce noise.
Up until recently we haven’t done a lot of testing with the HDRx function with the Epic, as 13+ stops of dynamic range is plenty in almost every situation, at least the way I typically like to shoot. One of the main issues with motion HDR is that it’s just too much latitude, and once you bring the contrast back to where you want it, you could have shot the original image and graded it to look almost identical. What I wanted to try to show is how it can be thought of to reduce shadow noise more-so than just protect highlights, especially when the final image is meant to look low contrast. It’s essentially saying the same thing, but just thinking about it differently in terms of exposure since with digital you typically expose for the highlights and let the shadows fall where they may – or add more light to these areas of the scene.
