I understand how to use Affinity Photo to create 3D LUTs for use in my video editing software Premiere Pro CC 2018. But sInce I'm shooting video on a Panasonic GH5 in VLOG-L I should be creating the LUT adjustments in a LOG color space, at least that's what my research found. That option doesn't appear in Affinity Photo's "Color Format" drop-down menu. Is the LAB option an equivalent? Hoping you can help. Thanks, John.
