-Relative HDR using the HLG transfer function
+Relative HDR, using the HLG transfer function,
 must map SDR media white
 to the same luminance as is used
 to display the 75% HLG value.
 
 Issue: see also tables 3 and 4 in ITU Rec.2408-0
 
-Absolute HDR using the PQ transfer function
+Absolute HDR, using the PQ transfer function,
 should map SDR media white
 to 140 cd/m², the same luminance as is used
 to display the 54% PQ value.
 However, implementations may chose to incorporate
 a color re-rendering step (OOTF)
