Another attempt at HDR. Initial reaction from this approach is that my footage is still too over exposed and a bit too soft.
But I'm closer than I was my last attempt. Here's what I tried:
I copied the original video layer three times giving you a stack of four videos.
Composite mode - Linear light, opacity 100%, desaturate slightly
Composite mode - Subtract, Invert stack (I used "Negative" filter), and opacity at 81%
Composite mode - Screen, Gaussian blur (very subtle), opacity at 51%
Then I sharpened the entire compound clip, or nested sequence
