Yes, you could simply color in the eyes on a dog's photo with a black marker. However, here's another trick that would probably have your family rewarding you with fabulous treats! Be certain to scan the original "bad eyes" photo at a high resolution, perhaps about 800dpi or more, so that when you zoom in on the digital file to edit the eyes you see smoother edges instead of pixels (tiny square boxes). Grab another good photo of it's eyes, scan that "good eyes" photo at a high resolution as well, then select the eyes (one at a time) from the new "good" photo's digital file and move them to cover up the glowing orbs in the "bad" photo. Or you could use the photo editing tool that is supposed to fix pets' eyes...but it's not a guarantee. Or, in this instance, these eyes came from a photo of a totally different dog. Be creative in rescuing such darling photos of furry family members.
