Premiere Pro's Curves feature allows you to make quick and precise color adjustments to achieve natural-looking results. The two types of curves you can use to edit color are: RGB Curves and Hue Saturation Curves.
You can edit curves using two approaches:
- Using the RGB Curves available in the Lumetri Color panel.
- Using the RGB Curves effect available in the Effects Control panel.
RGB Curves let you adjust luma and tonal ranges across the clip using curves. The master curve controls the Luma. Initially, the master curve is represented as a straight white diagonal line. Adjusting the master curve adjusts the values of all three RGB channels simultaneously.
You can add warm tones to a video clip using the RBG Curves. In this example, the white, and red lines are used to increase the warm tones in the clip. The blue and green lines are used to decrease the presence of blues and greens in the clip. A reddish tint is added to the clip making it appear warmer.
Premiere Pro offers the following color hue saturation curves that you can use to make different types of curve-based color adjustments to your clip.
- Hue versus Saturation - Select a hue range and adjust its saturation level.
- Hue versus Hue - Select a hue range and change it to another hue.
- Hue versus Luma - Select a hue range and adjust the luma.
- Luma versus Saturation - Select a luma range and adjust its saturation.
- Saturation versus Saturation - Select a saturation range and increase or decrease its saturation.
You can adjust colors using control points. While moving a control point, a vertical band appears to help you judge your final result.
With one of the color curves tabs open, click the Eyedropper tool to sample a color in the Program Monitor. Three control points are automatically placed on the curve.
- The center point corresponds to the color you selected.
- For the Hue curves, the value for the selected pixel is the Hue.
- For the Luma and Sat curves, the selected pixel corresponds to the Luma and Sat values.
By default, the Eyedropper samples a 5 x 5 pixel area and averages the selected color. Press the Cmd (macOS) or Ctrl (Windows) keys while using the Eyedropper to sample a larger 10 x 10 pixel area.
Premiere Pro processes effects that are applied before the current Lumetri effect before sampling the color.
- If the effect applied earlier affects the color, the changed color is sampled.
- Effects applied after the current Lumetri effect are not considered when sampling the color.
- The Lumetri panel process from top down. Basic, Creative, and RGB Curves are processed before feeding into the Hue Saturations Curves.
- Lumetri sections that come after curves (Color Wheels, HSL Secondaries, Vignette) are not considered when sampling the color.
- The Hue Saturation Curves process in parallel. All the curves sample the color value at the time it feeds into the Hue Saturation Curves section.
An example to illustrate this behavior:
Use the Hue versus Hue curve to change a green color into blue. Now, use the Hue versus Luma curve to sample the resulting blue color. Premiere Pro adds the control points to the green section of the curve - the original color - not blue.
If you want to ignore the Hue versus Hue change while editing the Hue versus Luma curve, deselect the check box above the Hue versus Hue curve.
This curve lets you selectively edit the saturation of any hue within an image. In this example, this curve has been used to increase the saturation levels of the image making the girl look less pale. The saturation of the blue sky and the light has also been increased to make the image as a whole look warmer.
This curve allows you to change a hue to another hue. In the above example, this color curve has been used to change the hue of the girl's dress.
You can also use this curve to quickly make minor but dramatic adjustments to color. For example, you can select yellowing leaves on foliage and change them to green to make the foliage look more healthy.
This curve lets you increase or decrease the lightness of specific colors. In the above example, the pale blue sky and its reflection in the water below has been darkened to add more drama to the image.
Adobe recommends using this curve with high-quality footage, as this can reveal pixelation or artifacts (if the original image quality is not good).
This curve lets you selectively manipulate image saturation. In the above example, this curve is used for desaturating only the oversaturated blue wall without affecting the similar less-saturated picture of the dolphin in a similar blue color.
Another great use of this curve is for ensuring broadcast legal saturation levels by desaturating everything above 75% saturation.
