Dual ISO - massive dynamic range improvement

it is used in the true camera. Will it be useful for render?

Blender doesn’t have the limitations of realworld cameras, you always have access to the full dynamic range of the scene.

Computer image rendering is only limited by working color space.
In digital photography i prefer Sigma’s foveon tech, but am still user & a fan of analog film.
