Test note · EOTF tracking

Filmmaker and Cinema are closest to the reference, although they slightly darken shadows and midtones. In Cinema, reducing Peak Brightness to Medium or Low increases this darkening. Standard brightens midtones considerably and compresses highlights. Brightness falls sharply in scenes that illuminate much of the screen.
