While humans may be under attack from the devilish "red-eye" effect when a camera's flash clashes with your portrait lighting situation, your furry friends suffer a different look--yellow eye. Because of the eye make-up of some animals, especially cats and dogs, their eyes take in and reflect a flash differently, causing an alien-like yellow glow in your otherwise perfect picture. Correct yellow eye with a few quick clicks in a graphics program such as Adobe Photoshop and put your pet's peepers back on display.
Open Photoshop, click the "File" menu and click "Open." Browse to the photo with the yellow eyes to fix and double-click the file, which opens in the Photoshop workspace.
Click the "Window" menu and click "Layers" to open the "Layers" palette, featuring a single layer called Background.
Click the "Magnify" tool on the bottom of the "Tools" palette and zoom in one of the eyes.
Click the "Lasso" tool and draw an outline around the glowing part of the eye; you'll be working on one eye at a time. When you see blinking dotted lines, right-click inside them and select "Layer via Copy." Notice a new Layer 1 is added to the "Layers" palette.
Click the "Image" menu, click "Adjustments" and select "Hue/Saturation." Drag the "Hue/Saturation" window to the right so you can see both it and your image.
Slide the "Saturation" bar to the left slowly, reducing the amount of yellow in the eye. Slide the "Lightness" bar to the left, taking away some of the glow and darkening in the eye. Slide the "Hue" bar to the left or right to recolor the eye from yellow to the pet or person's natural eye colour. Write down the numbers in all three boxes on the window and click the "OK" button.
Click the Background layer on the "Layers" palette and repeat the "Lasso," "Layer via Copy," "Image," "Adjustment" and "Hue/Saturation" process. Instead of using the "Hue/Saturation" slider bars, type in the numbers you wrote down to ensure you get the two eyes the exact same colour. Click the "OK" button when satisfied.
Click the small lined icon at the top right of the "Layers" palette. Select "Flatten Image." All three layers combine into one.
Click the "File" menu, click "Save As" and type a new name for the photo. This ensures you're able to access the original if desired.
