Filmic Modifiers

Within this menu, you will find many settings pertaining to the filmic tonemapping operator that Continuum utilises. Through these settings, the user has direct access to many of the values that drive the internal ACES curve, providing a total sense of control over how the final image appears.


Toe

Toe can be used to influence the intensity of the low point within the image. Higher values for Toe bring blacks out a lot more, while lower values tend to crush blacks within the image.


Slope

Slope controls the general slope of the curve, as per the name, and as such influences both low and high points within the image.


Shoulder

Shoulder works very similarly to Toe, however rather than operating on the low point, Shoulder instead operates on the high point within the image. This means that a higher value for Shoulder will bring out the high lights within the image, while a lower value will crush the high lights. The interesting thing with Shoulder, though, is the only object within the scene that is bright enough for Shoulder to influence it is the sun.


Black Clip

Black Clip results in a similar end result to Toe, however it behaves a little differently. While Toe is clipped such that colors cannot drop below 0, Black Clip instead allows colors to drop below 0. While this isn't very useful on monitors that can only display colors within the 0 to 1 space, and especially so with negative colors, it gives more control over the image to the user.


White Clip

White Clip influences the curve in the same way as Black Clip, however operates on the high point of the curve instead of the low point.


Gamut Expansion

Gamut Expansion provides an approximate high dynamic range color space for colors to be represented in, allowing colors to exceed the 0 to 1 color space, and still be displayed on low dynamic range monitors. This is done by mapping colors that exceed the 0 to 1 color space, to colors within the 0 to 1 color space, taking into account the influences to saturation that occur with a high dynamic range value.
