The Exposure tool modifies the amount of light passed to the next Tool. The light value is calibrated in stops like a camera exposure control and can be adjusted by up to plus or minus 16 stops.
Stops: With a 1.0 gamma, each positive stop doubles the amount of light, each negative stop halves it.Back to Matte Tools
The Color Filter tool creates a color overlay filter, like that used in a matte box, where the imposed color typically darkens the image. An integrated exposure adjustment can be used for brightness compensation.
Color: The color of the filter, which is typically bright and saturated.
Exposure Compensation: Corrects for any resulting changes in overall exposure.Back to Matte Tools
The Gradient tool adds a colored tint, like a matte box gradient, with control over color, falloff, and strength. On-screen overlay controls let you position the effect easily.
Stops: With a 1.0 gamma, each positive stop doubles the amount of light, each negative stop halves it.
X1, Y1, X2, Y2: Establishes the positions of the start and end of the gradient.
Falloff: Weights the gradient toward one end or the other of the gradient.
Strength: Specifies the extent to which the effect is applied.
Exposure Compensation: Corrects any resulting changes in overall exposure.
Color: The color of the filter, which is typically bright and saturated.Back to Matte Tools
The Diffusion tool adds a diffuse glow with control over size and emulation of filter grades. Color offset lets you add a tint to the glow effect in order to emulate a tinted diffusion filter.
Size: The range of diffusion, as a percentage of total image size.
Grade: Adjusts the softness of the diffusion grade.
Glow: Amount of luminance/bloom added to highlights.
Highlights Only: The extent to which operation is restricted to the brightest regions of the image.
Highlight Bias: A lower number pushes more of the image into the Highlights region.
Exposure Compensation: Corrects for any resulting changes in overall exposure.
Color: Tints the glow area.Back to Matte Tools
The Star Filter tool generates 2-point star shapes on over-bright areas of an image, emulating the look of a star filter on a real camera.
Size: Sets the size of the stars, as a percentage of the screen size.
Threshold: The luminance level above which highlights are picked up by the flare. Lower it to get more flare effect.
Threshold Softness: Introduces softness into the boundaries of the Threshold region, softening the overall flare effect naturally.
Boost: Lifts the white values in the image to create brighter stars.
Angle: Controls the angle of the stars.
Color: Shifts the color of star from the over-bright color tint toward a pure color.
