Luma - Native HDR and more

Luma aims to rewrite the game post processing phase to drastically improve the look without drifting too much from the original artistic vision.

The highlight feature is adding Native HDR support, which is not the same as the fake official HDR implementation.

Luma goes beyond enabling simply 10bit/16bit buffers by extensively rewriting and reverse-engineering various aspects of the game's rendering engine. As a result not only is HDR now properly displayed, but includes other aspects such as gamma correction, improved color grading, and user-accessible brightness, contrast, and saturation controls.

Benefits are not restricted to HDR users, all LUTs are now normalized at runtime without needing any content changes, banding is gone, there's gamma correction, improved film grain and more.

Luma was created by 4 HDR passionate developers (Ersh, Pumbo, Lilium, ShortFuse), whom all took on different roles to achieve this expansive refactor.

It is a follow up to the "Native AutoHDR and Color Banding Fix" mod (Ersh), which just increased the quality of the game buffers to 10bit+, leaving more room for AutoHDR solutions to work.

It is a spiritual successor to the CONTROL HDR mod (Pumbo).

It includes an improved version of the "Normalized LUTs" mod (ShortFuse).

It was built by using the HDR analysis ReShade shaders (Lilium).

HDR screenshots are available as file in the downloads.

• []Native HDR (both HDR10 and scRGB formats supported)

  []Increased buffers accuracy, reducing banding all around (SDR is now 10bit instead of 8bit)

  []Normalized/corrected LUTs, the grey flat look is mostly gone, while the color tint is retained

  []Fixed bink pre-rendered fullscreen videos playing back with the wrong colors and made them use AutoHDR

  []Improved the sharpening passes

  []Improved film grain to be more realistic and nice to look at (e.g. rebalancing the grain size and strength on dark/bright colors)

  []Fixed the game using very wrong gamma formulas

  []Customization settings for you to personalize the game visuals (all of the features above are adjustable at runtime)

  []More!

  []Starfield "official" HDR (Windows 11 AutoHDR): Starfield does not officially support HDR, both the Xbox Series and Windows 11 versions rely on the OS AutoHDR, meaning that the game still outputs 8bit SDR, and its visual quality is still bottlenecked by that (no proper highlights, no BT. 2020 colors, banding).

  To clarify, Windows AutoHDR is a simple post process filter that generates an HDR image out of an SDR one, but it interprets games using the wrong gamma (sRGB instead of 2. 2), and doesn'
