Fixing Red Eyes

These methods will also work with a variety of other situations but, here are three basic methods to fix images with red eyes. With this method we do assume that the Info Palette is used to measure and ultimately achieve the correct eye color.

Tip # 1

Use a Selection to copy and paste one Channel into another Channel of the same image.

A. CMYK images

1a. Create a Selection over the red eye areas. Feather them using 2 to 4 pixels. View one of the Channels such as Yellow and copy it to the clipboard (use command/control C). In this example we choose the Yellow because it was not completely solid image area.

2a. Then Paste the Yellow channel from the clipboard into one or two of the other Channels such as Cyan or Magenta (use command/control V).

• Experiment with this to get rid of red eyes. If the eyes get too gray use the Selection with Curves to alter the color.

B. RGB Images

The methods for working with RGB images to remove red eye are exactly the same as CMYK except for the channels that are used.

1b. Create a Selection over the red eye areas. Feather them using 2 to 4 pixels. View one of the Channels such as Blue and copy it to the clipboard (use command/control C).

2b. Then Paste the Blue Channel from the clipboard into one or two of the other Channels such as Red or the Green (use command/control V).

Note: This can be an effective method to improve details in an image by pasting a channel with detail into another channel that does not have details and then using Curves to fine tune the color with in the Selected area.

Tip #2

Use Selections and Image Processing tools.

A. Use the Lasso tool and create a selection on each eye, feather them using 3 to 6 pixels.

Option 1

Use Curves to reduce and adjust the color in the red eye area.

Option 2

Use Hue & Saturation by moving the Hue slider in the Master Channel until the red color changes to a more natural color.

Option 3

Use Hue & Saturation by moving the Saturation slider to the left to desatuate the color and then use Curves to adjust and file tune the color of each eye.

Tip #3

Use the Dodge and Burn tool.

1. To begin using the Dodge and Burn method, open another view of the image through the NEW VIEW menu. Set up your monitor so you can see the eyes of both images.

• With this technique you will use Dodge and Burn on a gray scale Channel of one image, but view the result of the Dodge and Burn on the display of the color image. Use the Info Palette to verify the color results.

2. On one image display the Red or Cyan channel (use the keyboard short cut command 1). Apply the Burn option with the various exposure levels such as midtone with the correct size brush over the red eye area. Applying Burn on Channel one will reduce the Red in the eye. You will be able to view this on the color image display.

3. Experiment with Dodging the other Channels until the correct eye color is achieved. This takes some trial and error. Try different exposure levels, such as shadows and midtones, with the various size brushes.

Option

Another option with this tool is to use the Sponge tool with the Desaturate mode. This will reduce the red eye. Then work on different Channels by Dodging them until the correct eye color is achieved.
