A Reinhard based tonemapping I recommend

I've done a tone mapping that looks like this: n/(n+exp(n/(n+1)))
This uses Euler, something that is widely used for natural products, and I've done a small test and look how it looks:

What do you think, would you add it? I think it looks more natural than the classic Reinhard. It's based on Reinhard.

Review the proposed Reinhard-based formula and the attached screenshot, then compare it with the project's existing tone-mapping options. Determine where tone mapping is implemented and tested before proposing the required API, behavior, and validation; done means the project has a decided approach and tests or visual evidence for the new mapping.
