I think it is necessary to render to HDR and use perceptual tone mapping as a post effect to simulate the dynamic range that the eye can perceive in the limited range that a regular display or a camera can handle.
As a simple example, this is how the eye would perceive a scene:

And this is how a camera would see it:

Of course, to get that dynamic range in an image, it has to be in the scene to begin with. Throw away pre-made light sets and build your own.
