Modifying Brightness in the Entire Image
Adjusting Printer Lights for Primary Grading
Modifying Brightness in the Shadows, Midtones, and Highlights
When you modify brightness, colours appear to emit more or less light. You can modify brightness across the entire image or just in the shadows, midtones, and highlights. You can also view and make printer light adjustments. Reset the brightness settings to their original values at any time.

If you want to modify R, G, B curves individually and within a particular range, use the RGB curves. See Modifying Red, Green, and Blue Channels.
You can increase or decrease colour brightness across the entire image. Use the Brightness slider to modify the brightness of the red, green, and blue levels uniformly. Use the Brightness Balance wheel to balance colours, remove or add a colour cast, create a sense of time, or create ambience. When you use the Brightness Balance wheel, you modify RGB levels proportionally without changing the overall brightness. For example, if you drag the Brightness Balance wheel toward blue, blue will appear to emit more light while red and green will appear to emit less; the image may therefore develop a blue cast.
Note: When you use a slider or colour balance wheel to colour grade a shot, the colour range is limited by the control (the edge of the colour wheel, for example). Use either the Autodesk control surface or the Tangent CP100 control surface to reach the full spectrum of colour.
Indicate whether this is the initial or final primary grade:
To work on the initial primary colour grade, click Input.
To make final adjustments to the primary colour grade, click Output.
Modify the overall brightness:
To increase the overall brightness in the image, drag the Brightness slider up.
The colours in the image appear to emit more light. The printer light settings are also updated to reflect your changes.
To decrease the overall brightness in the image, drag the Brightness slider down.
The colours in the image appear to emit less light.
To balance the colours in the image, create ambience, or develop a colour cast, enable Brightness and then drag the Brightness Balance wheel towards the colour you want to increase in the image. For example, to create a cooler image, drag toward blue; to create a warmer image, drag toward red.

The colours are balanced in the image without affecting the overall brightness. The printer light settings are also updated to reflect your changes.
Hint: When you click on the printer lights, the printer light values are replaced by values based on the center point of the colour wheel.
Make adjustments to the image using the Brightness slider and Brightness Balance wheel until you are satisfied with the results.
Hint: When working with any of the vertical sliders in the Grading menu, refer to their numerical values in order to make more precise adjustments. The default value for each of the sliders reflects the mid-point in the range of available values. For example, the Brightness slider has a range of -25 to 25, and a default mid-point value of 0. The Contrast slider, on the other hand, has a range of 0 to 2, making for a mid-point default value of 1.
You can make printer light adjustments to the entire image when you want to grade your shots according to printer lights and fstops. You can adjust the level of the overall colour brightness or the level of the RGBCMY values independently. You can then send the printer light settings to the film lab for processing. Printer light steps are set in the Display & Interface page of the user configuration. See Display & Interface Settings.
Note: Hot keys for printer light adjustments only work in Log mode.
Indicate whether this is the initial or final primary grade:
To work on the initial primary colour grade, click Input.
To make final adjustments to the primary colour grade, click Output.
Use the following keypad hot keys to make printer light adjustments to the image.

Note: Printer light settings do not include any modifications you make to brightness in the shadows, midtones, or highlights. See Modifying Brightness in the Shadows, Midtones, and Highlights.
Hint: When you click on the printer lights, the printer light values are replaced by values based on the center point of the colour wheel. If you then right-click one of the colour wheel values, the calculator appears in the UI, allowing you to enter a value.
You can increase or decrease the brightness in the shadows, midtones, or highlights. Use the Shadow, Midtone, or Highlight slider to modify the brightness of the red, green, and blue levels uniformly. Use the Low, Mid, or High Balance wheel to balance colours by modifying RGB levels proportionally.
Note: When you modify brightness in the shadows, midtones, or highlights, your changes are not reflected in the printer light settings.
Indicate whether this is the initial or final primary grade:
To work on the initial primary colour grade, click Input.
To make final adjustments to the primary colour grade, click Output.
Adjust the overall brightness:
To adjust the overall brightness in the shadows, drag the Shadow slider. Drag up to increase brightness. Drag down to decrease brightness.
To adjust the overall brightness in the midtones, drag the Midtone slider. Drag up to increase brightness. Drag down to decrease brightness.
To adjust the overall brightness in the highlights, drag the Highlight slider. Drag up to increase brightness. Drag down to decrease brightness.
Balance the brightness of colours:
To balance the brightness of the colours in the highlights, enable High and then drag the High Balance wheel toward the colour you want to increase in the image.
To balance the brightness of the colours in the midtones, enable Mid and then drag the Mid Balance wheel toward the colour you want to increase in the image.
To balance the brightness of the colours in the shadows, enable Low and then drag the Low Balance wheel toward the colour you want to increase in the image.

You can reset the image brightness using the keypad hot key.
Press - (minus sign) on the keypad.
The Brightness slider and Brightness Balance wheel are reset to their default settings. Printer light settings are also reset and the image reverts to its original printer light settings.
Note: Modifications you made to the image using the Brightness controls for shadows, midtones, and highlights are not reset to their default values. See Resetting Parameters.
