Today I learned how to remove red eye efect...just folow these steps..
1. Duplicate the background image layer so that if you mess up, you can easily return the image to its original state.
2. Select the Sponge tool from the toolbox.
3. On the Options bar, set the Mode control to Desaturate and the Flow setting to 100 percent, as shown in the figure.
4. Choose a small, hard-edged brush. The brush should be smaller than the red-eye area you want to correct.
5. Click or drag over the red-eye pixels. The program sucks the color out of the pixels you touch, leaving them white, black, or gray.
6. Create a new, empty layer by clicking the new layer icon in the Layers palette.
This layer will hold your new eye color. Set the layer blending mode to Color by using the menu at the top of the Layers palette
7. Click the foreground color icon and choose a color thatâs close to the subjectâs natural eye color.
8. Activate the Paintbrush tool. Again, use a small brush, but this time you may want to work with a soft brush tip so
that your paint strokes donât have hard edges.
9. Dab on the new eye color as needed. If you donât see any change, as may be the case when working on animal eyes, switch the blending mode to Normal and reduce the Opacity setting in the Layers palette to about 50 percent.
10. When youâre happy with your work, merge the image layers by choosing Layer-Flatten Image.
You can use this same approach with any program that offers a Sponge tool, layers, and the layer blending mode. Donât have any of those tools? If your photo editor offers a hue/saturation filter, try this fix instead: Select the red portion of the eyes and then adjust the color by using the hue control. You also may be able to use a regular color balance filter, which is a basic filter found in every photo editor.
