However, these tools don't always work on pets since they can have yellow, white, red, or green eyes in photos taken in low-light conditions with a flash. Learn how to fix glowing pet eyes in Gimp, Photoshop, and similar programs. Instructions in this article apply broadly to all desktop photo editing software. How to Fix Pet Eyes in Photos The following screenshots come from Gimp, an open-source image editor for Windows, Mac, and Linux, but the general process is the same for other programs. Open the image in your editing software and follow these steps: Create a new transparent layer in your document, making sure the Mode is set to Normal. Select the paintbrush tool and choose a medium-soft edge brush. Set the foreground color to black, and set the size slightly larger than the eye pupil. You might need to use an elliptical brush shape when dealing with cat eyes. Zoom in and click on each eye to paint over the pet eye reflections. You might need to click a few times with the paintbrush to cover the entire problem area. At this point, the eye will look strange because there is no glint of light reflection in the eye. Temporarily hide the layer where you painted black over the eye in the last step. In Gimp, select the eye icon next to the layer in the Layers palette. To make the eyes look natural, replace the reflected points of light you painted over in the previous steps. Select a hard-edge brush, set the size to very small (about 3 to 5 pixels), and set the foreground color to white. Create another transparent layer in the document above all other layers in the document. With the painted layer hidden, you should be able to see the original photo. Make a note of where the glints appear in the original photo and click once with the paintbrush directly over each eye glint in the original. Unhide the black paint layer to see the final result. If it doesn't look natural, clear the layer, and keep trying. If the image is acceptable, save and export it to your preferred image format. You can add a slight amount of Gaussian blur on the black paint layer to blend the pupil into the iris. Use the eraser tool to clean up the black paint that went outside of the eye area onto your pet's fur. In some cases, the pet eye is so bad that you can't find the original eye glints. You'll have to guess where they should be based on the direction of the light and how other reflections appear in the photo. Keep both eye glints in relation to each other for both eyes. If you can't make a solid guess on the location of the glints, start with the centers of the pupils.
