  • Good sharpness and a very versatile format for PC and console.

Things to consider

Test note · EOTF tracking

Tracking is reasonable in some midtones, but the darkest shadows are raised and highlights are compressed at the brightness limit. The HDR image also has a cool cast, with excess blue in grayscale.
