HLG Still Image
By using gamma characteristics equivalent to HLG (Hybrid Log-Gamma: standard for HDR images), you can shoot still
images with a wide dynamic range and a wide color gamut compatible with BT.2020.
[HLG Still Image] can only be set when shooting in the HEIF format. Set [JPEG/HEIF Switch] to [HEIF(4:2:0)] or
[HEIF(4:2:2)], and [ File Format] to [HEIF] beforehand.
MENU → (Shooting) → [Image Quality] → [HLG Still Image] → desired setting.
