Filmulator is a raw photo editing application with library management that simulates the film development process as if the digital sensor had exposed the same light as a photographic negative. Large bright regions become darker, compressing the output dynamic range. Small bright regions make their surroundings darker, enhancing local contrast. In bright regions saturation is enhanced, helping retain color in skies, skin tones and sunsets. In extremely saturated regions the brightness is attenuated, helping retain detail in subjects such as flowers or textured surfaces.
