Download Filmic Tonemapping DELUXE FREE Unity. 

Filmic Tonemapping Deluxe brings a powerful and easy to customize tonemapper to Unity. It is based on a truly flexible and intuitive H&D sensitometry curve calibrated for games instead of an unadaptable low-quality approximation used by most other tonemappers (ACES approximation, Hable, Photographic, …).

It will make your game and scene look more physically accurate by adding depth to the colors where it matters.

Since version 1.2, a high-quality histogram-based eye adaptation effect has been added. This effect is able to simulate how human eyes adapt to lighting while keeping an optimal contrast and white point.
