Add a vignette to a photo

You can change the look of a photo by darkening its edges with a vignette. The vignette changes the focal point of an image, emphasizing the center of the image. You can adjust the darkness and size of a vignette to create the look you want, and soften the vignette for a less dramatic effect.

    • Softness: Changes the opacity of the vignette, making it more or less pronounced.

Adjust white balance

If there’s an area in a photo that you know should be white or gray, but appears off-color, you can balance the photo’s overall color (known as color cast). Sometimes photos may have an undesirable cast due to lighting conditions—for example, a photo may have a yellow or orange cast from the light fixtures in the location where the photo was taken. By changing white balance, you can adjust the white areas in a photo to remove the color cast and make them appear more white.

Photo before and after white balance adjustment
  1. Double-click a photo, then click Edit in the toolbar.

  2. Click the Adjust button Adjust button.

  3. In the Adjustments pane, click the Add button and choose White Balance.

  4. Click the pop-up menu and choose the type of white balance correction you’d like to make. Then click the Auto button to automatically correct those colors, or click the Eyedropper button Eyedropper button and click the eyedropper in a corresponding area of the photo.

    White Balance controls in the Adjustments pane
    • Neutral Gray: Balances the warmth of an image based on natural gray.

      Click the eyedropper in a neutral gray area in the photo to automatically adjust the gray areas of your photo.

    • Skin Tone: Balances the warmth of an image based on skin tones.

      Click the eyedropper in a person’s skin in the photo to automatically adjust the skin tones of your photo.

    • Temperature/Tint: Balances the warmth of an image by adjusting color temperatures (blue-to-yellow) and tint (green-to-magenta).

      Click the eyedropper in a neutral gray area in the photo to automatically adjust the temperature and tint of grays of your photo.

Adjust levels

You can adjust the levels in a photo to control the tonal range and contrast of the photo. You can adjust settings for the black point, shadows, midtones, highlights, and white point. You can also change the look of specific colors (red, green, and blue).

    • Change the histogram to display Luminance values (instead of RGB values): Hold your pointer over the histogram and click the Levels button Levels button at the top right, then choose Luminance. For example, you might want to change the histogram to luminance values when working with black and white photos. The histogram handles perform the same functions as when the RGB histogram appears.

Note:  You can also drag the top handles of the level controls to change the range of adjustment. For example, to adjust only the lightest of highlights, move the top handle further to the right. To fine-tune an adjustment, hold down the Option key and then drag the bottom handle. This moves both bottom and top handles in unison until you get the results you want.
