This is so much better than the limitations inherent with the HDR Exposure dial on my panel. Having access to exposure level, fill exposure, fill roll-off, and being able to see the fill curve is a great addition. Another thing that speeds things up are the PowerGrades that you can pull over with various preset stops +/-. With Live Preview engaged, you can roll across the Powergrades and find a nice starting point. It might be nice to have .25 +/- stops in the future, but that would be my only suggestion, and you can make a .25 stop version yourself in seconds. It’s now in my standard node tree. Nice work, PT.
