Sean_Conley hey Sean, the ettl rec709 lut simply makes the image brighter than the standard rec709. No need to use this lut, simply setup dehancer and use the exposure slider to het the exposure in the right ballpark. Please let us know if you have any questions about dehancer. Generally we use dehancer in the middle of our node three.
First exposure and contrast correction, wb correction , tint and matrix and powermasks, 2nd dehancer as film matrix but no grain or Bloom or halation, then secundairy grading like even color contrast setups etc, and finally as last dehancer for print film grain, halation Bloom etc.
