(High bit-depth) The Fast Color Corrector effect adjusts a clip’s color using hue and saturation controls. The effect also has levels controls for adjusting intensity levels of image shadows, midtones, and highlights. This effect is recommended for making simple color corrections that preview quickly in the Program monitor.

Output

Lets you view adjustments in the Program monitor as the final results (Composite), tonal value adjustments (Luma), or display of the alpha matte (Mask).

Show Split View

Displays the left or upper part of the image as the corrected view and the right or lower part of the image as the uncorrected view.

Layout

Determines whether the Split View images are side by side (Horizontal) or above and below (Vertical).

Split View Percent

Adjusts the size of the corrected view. The default is 50%.

White Balance

Assigns a white balance to an image using the Eyedropper tool to sample a target color in the image or anywhere on your monitor’s desktop. You can also click the color swatch to open the Adobe Color Picker and select a color to define the white balance.

Hue Balance And Angle

Controls hue and saturation adjustments using a color wheel. A circular thumb moves about the center of wheel and controls the hue (UV) translation. A perpendicular handle on the thumb controls balance magnitude, which affects the relative coarseness or fineness of the control. The outer ring of the wheel controls hue rotation.

Adjustments to the Hue Balance And Angle can be viewed in the vectorscope.

Hue Angle

Controls the hue rotation. The default value is 0. Negative values rotate the color wheel to the left and positive values rotate the color wheel to the right.

Balance Magnitude

Controls the amount of color balance correction as determined by the Balance Angle.

Balance Gain

Adjusts brightness values by multiplication so that lighter pixels are affected more than darker pixels.

Balance Angle

Controls the selection of desired hue value.

Saturation

Adjusts the image’s color saturation. The default value is 100, which doesn’t affect the colors. Values less than 100 decrease saturation, with 0 completely removing any color. Values greater than 100 produce more saturated colors.

Auto Black Level

Raises the black levels in a clip so the darkest levels are above 7.5 IRE (NTSC) or 0.3v (PAL). A portion of the shadows is clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto Black Level lightens the shadows in an image.

Auto Contrast

Applies both the Auto Black Level and Auto White Level simultaneously. This makes the highlights appear darker and shadows appear lighter.

Auto White Level

Lowers the white levels in a clip so the lightest levels do not exceed 100 IRE (NTSC) or 1.0v (PAL). A portion of the highlights is clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto White Level darkens the highlights in an image.

Black Level, Gray Level, White Level

Sets the levels for darkest shadow, midtone gray, and lightest highlight using the different Eyedropper tools to sample a target color in the image or anywhere on your monitor’s desktop. You can also click the color swatch to open the Adobe Color Picker and select a color to define the black, midtone gray, and white.

Input Levels

The outer two Input Levels sliders map the black point and white point to the settings of the Output sliders. The middle Input slider adjusts the gamma in the image. It moves the midtone and changes the intensity values of the middle range of gray tones without dramatically altering the highlights and shadows.

Output Levels

Map the black point and white point input level sliders to specified values. By default, the Output sliders are at level 0, where the shadows are completely black, and level 255, where the highlights are completely white. So, in the default position for the Output sliders, moving the black input slider maps the shadow value to level 0, and moving the white point slider maps the highlight value to level 255. The remaining levels are redistributed between levels 0 and 255. This redistribution increases the tonal range of the image, in effect increasing the overall contrast of the image.

Input Black, Input Gray, Input White

Adjust the black point, midtone, and white point input levels for the highlights, midtones, or shadows.

Output Black, Output White

Adjust the mapped output levels for the input black and input white levels for the highlights, midtones, or shadows.
