Thanks @jogal for your continued work on all things HDR & DirectX related, and especially for this. When Tone Mapping was introduced it was recognised at the time that Reinhard would only provide a basic level of tone mapping, so it was always envisioned that there might become a variety of algorithms available to the user over time, so the Team is really pleased to see this happen even if it's just for Windows at the moment.
