What is Red Eye?
Red eye is a common phenomenon that occurs when the flash of a camera reflects off the back of a person’s eye and appears as a red or orange glow in photographs. This phenomenon can affect the appearance of the eye, giving it a demonic or unnatural look. Red-eye occurs because the flash of a camera is often too close to the lens, causing light to enter the eye and bounce off the blood vessels in the retina.
Typically, red eye is more prominent in low-light situations where the pupils are dilated. The light from the camera flash passes through the pupil and illuminates the retina, causing the blood vessels to reflect the light back. This reflection creates the appearance of red or orange eyes in the photograph.
Red eye can be particularly noticeable in individuals with lighter eye colors, such as blue or green, as the pigmentation in the iris is less able to block the reflective light. However, individuals with darker eye colors can also experience red-eye, although it may be less pronounced.
It’s worth noting that red eye is not exclusive to humans. Certain animals, such as cats and dogs, can also exhibit red-eye in photographs due to a similar anatomical structure of their eyes.
Understanding the causes and mechanisms behind red eye is essential for effectively removing or reducing its appearance in photographs. In the following sections, we will explore the manual process of removing red eye in Adobe Photoshop.
Why Does Red Eye Occur?
Red eye is a common occurrence in flash photography, and understanding why it happens can help us prevent and remove it effectively. There are several factors that contribute to the occurrence of red eye:
- Anatomy of the Eye: The anatomy of the human eye plays a significant role in the occurrence of red eye. The retina, located at the back of the eye, contains blood vessels that can reflect light when illuminated by a camera flash.
- Low Light Conditions: Red-eye is more likely to occur in low-light settings when the pupils are dilated to allow more light into the eyes. With dilated pupils, the camera flash can penetrate deeper into the eye, hitting the retinal blood vessels and causing them to reflect light more prominently.
- Camera Flash Position: The proximity of the camera flash to the lens can greatly influence the occurrence of red eye. When the flash is too close to the lens, the light from the flash directly enters the eye, hitting the retina and causing reflection.
- Eye Color: Individuals with lighter eye colors, such as blue or green, tend to have a higher susceptibility to red eye due to the reduced pigmentation in their irises. The lack of pigmentation results in less absorption of light, making the blood vessels in the retina more visible.
It’s important to note that modern digital cameras often include red-eye reduction features that emit a pre-flash before taking the actual photograph. The purpose of this pre-flash is to cause the subject’s pupils to contract, reducing the chances of red eye. However, even with these features, red-eye can still occur in certain situations.
Understanding the reasons behind red eye can help us take preventive measures to minimize its occurrence. In the next section, we will explore the manual process of removing red eye in Adobe Photoshop, allowing us to correct this issue and achieve more natural-looking photographs.

Once you have selected the Red Eye Removal tool, you will notice a few options in the options bar at the top of the Photoshop workspace. These options allow you to customize the size of the pupil and control the darkening amount for an accurate and natural result.
Before proceeding with the red eye correction, make sure the tool’s size matches the size of the pupil. You can adjust the pupil size by dragging the Pupil Size slider in the options bar. It’s important to make the tool slightly smaller than the pupil to ensure precise editing.
In addition to adjusting the pupil size, you can also control the darkening amount of the correction. The Darken Amount slider in the options bar allows you to adjust the intensity of the color correction. Increase the value if the red eye effect is still visible or decrease it if the correction appears too strong.
By selecting the Red Eye Removal tool and customizing the options according to the eye you’re correcting, you’re now ready to move on to the next step: adjusting the red eye pupil size in Photoshop.
Step 4: Adjusting the Pupil Size
After selecting the Red Eye Removal tool in Adobe Photoshop, the next step in the manual red eye removal process is to adjust the pupil size. This allows for precise editing and ensures that the correction matches the size of the affected pupil.
With the Red Eye Removal tool selected, you will find options in the tool’s options bar at the top of the Photoshop workspace. Locate the Pupil Size slider and use it to adjust the size of the tool.
It’s important to make the tool size slightly smaller than the pupil itself. This ensures that only the red portion is targeted for correction, while leaving the surrounding area untouched. Adjusting the pupil size accurately helps to achieve a seamless and natural-looking correction.
To decrease the pupil size, drag the Pupil Size slider to the left. As you move the slider towards the left, the size of the tool decreases. Experiment with different sizes until you find the best fit for the affected eye.
If the pupil size is too small, it may not cover the entire red-eye area, resulting in an incomplete correction. On the other hand, if the pupil size is too large, it might affect the surrounding parts of the eye, making the correction appear unnatural or distorted.
Take your time to adjust the pupil size until it aligns perfectly with the size of the affected pupil. This will ensure a precise and accurate correction that blends seamlessly with the rest of the eye.
Once you have adjusted the pupil size, you are ready to move on to the next step: adjusting the darkening amount to refine the red eye correction in Photoshop.
Step 5: Adjusting the Darken Amount
After adjusting the pupil size in Adobe Photoshop’s Red Eye Removal tool, the next step in the manual red eye removal process is to adjust the darkening amount. This adjustment allows you to control the intensity of the color correction.
In the options bar of the Red Eye Removal tool, you will find the Darken Amount slider. By dragging this slider, you can increase or decrease the darkening effect applied to the red-eye area.
Increasing the darkening amount helps to ensure that the corrected area blends seamlessly with the surrounding eye color. If the red eye effect is still visible after the initial correction, you may want to increase the darkening amount to make the correction more effective.
On the other hand, if the initial correction appears too intense or artificial, you can decrease the darkening amount to achieve a more subtle and natural result. Finding the right balance for the darkening amount is key to creating a seamless and realistic correction.
Keep in mind that the ideal darkening amount may vary depending on factors such as the intensity of the red-eye effect, the lighting conditions in the photograph, and the overall color balance of the image. Experiment with different darkening amounts to find the setting that best matches the appearance of the unaffected eye.
As you adjust the darkening amount, be mindful of not overdoing it. It’s important to maintain a natural look and avoid creating an unrealistic or overly darkened area in the eye. Continuously evaluate the results and make necessary adjustments until you achieve a visually appealing correction.
Once you have adjusted the darkening amount to your satisfaction, you are now ready to apply the changes and review the results in the next step of the red eye removal process.
Step 6: Applying the Changes
After making the necessary adjustments to the pupil size and darkening amount in Adobe Photoshop’s Red Eye Removal tool, it’s time to apply the changes to the red-eye area. The application of the changes will allow you to see the immediate effect of the correction and assess the results.
Position the mouse cursor over the red-eye area within the zoomed-in image and click once to apply the correction. Photoshop will automatically analyze the selected area and adjust the color to match the surrounding eye color.
As you apply the changes, observe the red-eye area closely to ensure that the correction looks natural and seamless. Take note of any remaining imperfections or inconsistencies that may require further refinement.
If the correction is not satisfactory, you can use the History panel or the Undo command (Ctrl+Z or Command+Z) to revert the changes and make further adjustments to the pupil size or darkening amount.
It’s important to be patient and attentive during this stage of the process. Carefully review the results and make any necessary tweaks to achieve a visually appealing correction that matches the appearance of the unaffected eye.
Remember that the goal of manually removing red-eye is to create a subtle and natural-looking correction. Avoid overcorrecting or making drastic changes that may result in an unnatural or artificial appearance.
By applying the changes strategically and considering the overall visual balance, you can refine the red-eye correction and bring the eye’s appearance back to its natural state.
Once you are satisfied with the applied changes and the overall result, proceed to the next step to review the final outcome of the red eye removal process in Adobe Photoshop.

Step 8: Saving the Edited Image
After successfully correcting the red-eye effect in Adobe Photoshop, the final step is to save the edited image. Saving the image ensures that the changes you made are preserved and can be accessed for future use or sharing.
To save the edited image, go to the “File” menu at the top of the Photoshop workspace and select “Save” or “Save As.” Alternatively, you can use the keyboard shortcut Ctrl+S (Windows) or Command+S (Mac) to quickly save the file.
If you choose “Save,” Photoshop will simply overwrite the original image with the edited version, keeping the same file name and format. It’s important to note that this action permanently replaces the original file, so make sure you have a backup copy if needed.
If you prefer to preserve the original image and create a new file for the edited version, choose “Save As.” This option allows you to specify a new file name, location, and file format for the edited image. It’s advisable to select a high-quality file format, such as JPEG or TIFF, to maintain the image’s quality and avoid any loss of detail.
When saving the edited image, consider adding relevant metadata, such as copyright information or descriptive tags, to provide context and protect your work.
Once you have chosen to save the edited image as a new file or overwrite the original, Photoshop will process the file and save it to the specified location. A progress bar will indicate the saving process, and once complete, you can close the image or continue editing further if desired.
With the edited image saved, you can now confidently share it, print it, or continue post-processing with other tools. The red eye removal process in Adobe Photoshop is complete, and you have successfully preserved the natural appearance of the eyes in your photograph.
