(Optional) Do any of the following to set preview options:
•
To view only the luminance values in a clip, choose Luma from the Output menu. This option affects only the
preview in the Program Monitor; it doesn’t remove the color from the video.
• To display a before and after view of the clip in one monitor, select the Show Split View option. You can specify
whether the split view is horizontal or vertical by choosing from the Layout menu. You can also adjust the relative
proportion of the before and after views.

(Optional) Click the triangle to expand the Secondary Color Correction controls if you want to correct the exposure

specify the colors to correct.

Do one of the following to make curve adjustments:
•
To adjust the luminance, click to add a point on the Luma or Master graph and drag to 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.
•
To adjust both the color and luminance using the RGB Curves effect, click to add a point on the appropriate graph
to adjust all color channels (Master), the red channel, the green channel, or the blue channel. Drag to change the
shape of the curve. Bowing the curve upward lightens the pixel values and bowing the curve downward darkens the
pixel values. The steeper sections of the curve represent portions of the image with greater contrast.
You can add a maximum of 16 points to the curve. To delete a point, drag it off the graph.
As you make adjustments, watch carefully for banding, noise, or polarization in the image. If you notice any of these,
reduce the value you are adjusting.
