    Would be great to see this feature implemented in HDRP.

    It's very useful especially for first and third person perspective video games with realistic lighting. I think that in the future it may become a standard for games that use physically based renderers like HDRP (rendering, cameras, lighting), especially with global illumination enabled and when realistic light intensities are used for sunlight and other light sources. It can make the visual experience smoother and more 'friendly' for the player as the final result and general perception is closer to how the human brain and eyes work.

    This would be immensely helpful. Even the simple HDRP template struggles with over exposure, let alone a bigger scene.

    Makes going from dark>bright, and bright>dark an absolute pain in general. Can even happen in an exterior scene with no interiors, with lightmaps as some areas are much darker than others.
