Film Look
An “all-in-one” film look node. Combines the Film Grain operation described above with
an “s-curve” exposure adjustment that slightly crushes the shadows and boosts the
highlights. Contrast in the midtones is stretched, but the distribution of the midtones
remains centered, so there’s no overall lightening or darkening. This node has three
parameters:
 Grain Intensity: Makes the noise more visible by raising its contrast ratio (inserting
both light and dark pixels of noise) as well as the saturation of the noise.
 Grain Size: Increases the size of each “grain” of noise that’s added. Bear in mind that
the size of the film grain is relative to the resolution of your project. Film grain of a
particular size applied to a standard definition shot will appear “grainier” than the
same-sized grain applied to a high definition shot.
 Contrast: Makes an “s-curve” adjustment to contrast, which crushes the shadows and
boosts the highlights, while leaving the midtones centered. A value of 0 preserves
the original contrast of the corrected image, while a value of 1 is the maximum
contrast expansion that is possible with this node.
Gain
Adjusts contrast by raising or lowering the white point of the image while leaving the
black point pinned in place, and scaling the midtones between the new white point
and the black point. This node has four parameters:
 Gain: Adjusts the red, green, and blue channels simultaneously, for an overall change
to image highlights and midtones.
 Red Gain: Adjusts the red channel only, enabling color correction based on a white
point adjustment for that channel.
 Green Gain: Adjusts the green channel only, enabling color correction based on a
white point adjustment for that channel.
 Blue Gain: Adjusts the blue channel only, enabling color correction based on a white
point adjustment for that channel.
Gamma
Makes a standard gamma adjustment, which makes a nonlinear adjustment to raise or
lower the distribution of midtones of the image while leaving the black and white
points pinned in place. This is a power function, (f(x) = x
a ). This node has four
parameters:
 Gamma: Adjusts the red, green, and blue channels simultaneously, for an overall
change to image midtones.
 Red Gamma: Adjusts the red channel only, enabling color correction based on a
gamma adjustment for that channel.
