USING ADOBE PREMIERE PRO 362 Effects and transitions Here's a link to a tutorial on www.premierepro.net that shows advanced color grading in Premiere Pro CS5.5 and later using (among other tools) the RGB Curves effect. 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 one part of the image as the corrected view and the other 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%. Master Alters the brightness and contrast of all channels when you change the shape of the curve. Bowing the curve upward lightens the clip and bowing the curve downward darkens the clip. The steeper sections of the curve represent portions of the image with greater contrast. Click to add a point to the curve and drag to manipulate the shape. You can add a maximum of 16 points to the curve. To delete a point, drag it off the graph. Red, Green, and Blue Alters the brightness and contrast of the red, green, or blue channel when you change the shape of the curve. Bowing the curve upward lightens the channel and bowing the curve downward darkens the channel. The steeper sections of the curve represent portions of the channel with greater contrast. Click to add a point to the curve and drag to manipulate the shape. You can adjust up to a maximum of 16 points on the curve. To delete a point, drag it off the graph. Secondary Color Correction Specifies the color range to be corrected by the effect. You can define the color by hue, saturation, and luminance. Click the triangle to access the controls. Note: Choose Mask from the Output menu to view the areas of the image that are selected as you define the color range. Center Defines the central color in the range that you're specifying. Select the Eyedropper tool and click anywhere on your screen to specify a color, which is displayed in the color swatch. Use the + Eyedropper tool to extend the color range, and use the - Eyedropper tool to subtract from the color range. You can also click the swatch to open the Adobe Color Picker and select the center color. Hue, Saturation, and Luma Specify the color range to be corrected by hue, saturation, or luminance. Click the triangle next to the option name to access the threshold and softness (feathering) controls to define the hue, saturation, or luminance range. End Softness Makes boundaries of the specified area more diffuse, blending the correction more with the original image. A higher value increases the softness. Edge Thinning Makes the specified area more sharply defined. The correction becomes more pronounced. A higher value increases the edge definition of the specified area. Invert Limit Color Corrects all colors except for the color range that you specified with the Secondary Color Correction settings.
