Coloring the Eye
There are many ways to Color a person’s eye in Photoshop. This method uses the natural color of the eye as a base for new Color. Start out by creating a New Layer and sampling the color from the inner part of the eye. Next open your color palette and increase both Lightness and Saturation. This will give you a more vibrant version of the same Hue. Then paint over the inner part of the eye, covering where the original Color was. Do this a couple of times, sampling Colors from around the eye.
After all of the Colors are painted, change your layer blending mode to “Soft Light” or “Overlay” to allow the color to blend into the eyes. Then make sure to use “Gaussian Blur” to Soften the edges of where you painted.
The eyes should be quite a bit more vibrant but still look natural.
Dodge and Burning the Eye
In this episode we use Curves Adjustment Layers to brighten the center part of the pupil and Darken the outer edges of the pupil. This change will give the eyes more Depth and Light.
The final step is to Sharpen the eyes. You may already be sharpening your whole image, but just sharpening key areas (like the eyes) is a great way to Draw more attention to those areas.
