Red Giant BulletProof

Auto Balance

Auto Balance is a color picker that removes a highlight color cast by sampling a close-to-white area in the clip. This will set a new color that balances out the Red, Green and Blue components, and makes that white area turn neutral.

When using Auto Balance, you are generally trying to compensate for a perceived color tone. If the color is too hot and you want to cool it down, then choose a blue color chip to turn the image more orange (its opposite on the color wheel).

Auto Balance only affects the shadows and highlights of your source footage. It does not adjust for the midtones. Click the Reset button to set the tool to its 0 position.

The BulletProof pipeline. Auto Balance is a terrific first step to fixing a color issue in your footage. If you use this control, it should be the first one you set, even before adjusting Colorista 3-Way settings.

Already know Red Giant? If you’re familiar with our Red Giant Colorista II and Magic Bullet Looks 2 products, then you will recognize Auto Balance. This tool functions the same in BulletProof as it does in Colorista and Looks. The only difference is that Auto Balance is a separate process in BulletProof that does NOT affect the values in the Colorista 3-Way tool.

 

 

Using the eyedropper

Our Auto Balance works differently than other balance controls that you may have used.

Set your white point. You don't click a button to have BulletProof figure out the white point. Instead, you use an eyedropper tool to explicitly define what you think the white point should be. Auto Balance then tries to correctly set the shadows and the highlights. The Auto Balance color chip reflects what it feels is the middle tone between the shadows and the highlights.

Corrects the black point too. Another unique aspect of our Auto Balance is that it corrects for both the white point and the black point. Typically, a balance control only corrects for the white point.

Workflow Tip! The most accurate way to sample a white point is to click in the sclera, the white area of someone's eye. Teeth are always too yellowish to use as a good sample. If the sclera is too much in shadows, as in our example below, then sample from the whitest possible point of your image.
