The primary source of red eye in images is light reflecting off the retina located in the back of the eye, which happens when the eye is directly illuminated by a camera flash. Because the retina has an abundant blood supply, the reflected light appears red. The proximity of the flash to the lens axis, the size of the pupil, and the angle between the camera lens and the flash are some of the factors that contribute to its prominence. Avoiding direct flash, turning on ambient lighting, or utilising camera anti-red eye capabilities are some methods for reducing red eye. Experience shows you how to make little changes for the best outcomes.

As red-eye incidents become less common due to the reduced popularity of flash photography,  they can still happen under certain circumstances. With the invention of strong photo editing tools like Adobe Photoshop and AI software like the renowned ZMO photo editor tool and generative fill, red flashes stand no chance of dampening the beauty of modern pictures. Let us investigate how to correct red eyes using Photoshop’s red-eye removal tool and ZMO. Let’s jump right in: 

How to Remove Red Eye with Adobe Photoshop: Manual Method

While red-eye effects in photos can be effectively removed by automated programmes, learning how to use Photoshop’s manual method gives you more control and accuracy over the cleanup process. Photographers can fine-tune alterations based on the specifics of each image by using manual removal, which guarantees a smooth and natural outcome. In this article, we’ll explore the finer points of manually eliminating red eyes in Photoshop, equipping photographers with the knowledge and abilities to carefully and meticulously improve the quality of their photos.

Step 1:

 Open the desired photo in Photoshop and begin working. To ensure accurate targeting for the manual removal process, zoom in on the image and concentrate just on the areas that are impacted by red-eye discoloration.
