The Red-Eye Effect in your photos is caused by lighting conditions and by the use of a flash

You would be amazed at how many photos I come across that are posted on Social Media that has the “Red Eye Effect”.

You would also be amased at how simple it is to avoid before taking the photo

But if any of your photos end up having red eyes.

There is a simple solution to correct them before posting them on Social Media.

It's as simple as painting a black dot over the red dot on each pupil, I will explain this here in this article.


The "red-eye effect" in photos is very annoying. It occurs mainly in photos taken in low light conditions and with the aid of a flash.

The reason for this is quite simple.

In a dark environment, the pupil opens so that as much light as possible enters the eye. To compensate for the poor lighting conditions and to brighten the image, many use a flash.

If the flashlight hits the eye almost on the same axis. It's reflected as red light by the well-perfused retina.

This happens especially when taking snapshots with compact digital cameras

where the flash is very close to the lens.

the undesirable red-eye effect can often occur.

I’ll first explain to you what you should pay attention to while taking a photo.

then how you can avoid the red-eye effect with the help of planning your composition.

The undesired "red-eye effect" can be avoided while taking the photo. Be it through external light sources or the use of the pre-flash function.

Here are 4 simple tips to avoid the red-eye effect.

1.Make sure there is enough light

At first, try taking the photo without a flash. Use external light sources that will help to make the surroundings as bright as possible.

Turn on lights in closed rooms or use lanterns for outdoor shots.

The more natural light there is available, the better. The smaller the pupil the less the flashlight will be reflected by the eye.

2.Activate Auto Flash

Many cameras have an Auto-flash or a "red-eye effect" mode.

Even if this special mode is not one hundred percent accurate.

You should always activate it, especially with compact digital cameras.

To assist this working the pre-flash, light reaches the eye before the actual flash.

which briefly closes the pupils and reduces the “red-eye effect”.

Let the other person know that there is a preliminary flash. Otherwise, it may leave its position after the first flash.

3.Use an external flash

The use of an external flash can reduce the “red-eye effect” when a flash cannot be avoided.

Especially if the flash is located in the camera.

It's better to disable the internal flash and have the external flash placed far from the lens.

Because the further away the flash is from the lens, the lower the likelihood of the red-eye effect in the photo.

4.Change the position of composition

As already mentioned at the beginning.

The “red-eye effect” occurs above all when the flashlight hits the eye almost on the same axis.

To avoid this happening. The person being photographed should not look directly into the camera.

Changing the direction of gaze can be enough to avoid unwanted the red-eye effect from the photos.


Unfortunately. It cannot always be avoided that the red-eye effect creeps in on your photos. If this is the case, the red-eye effect can be retouched with the help of digital image editing programs or apps.

For this purpose, many photo editing programs and apps. Have a special function to remove the red-eye effect with one click.

In the following video. I will show you how you can retouch the red-eye effect on an iPhone or iPad using the native iOS “Photos” app.

Similarly. this can also be done on android mobile & there are many “Third Party” apps available

Apps such as Adobe Lightroom, Adobe Photoshop Express, and many more on both Android and iOS mobile or Adobe Photoshop & Gimp on a desktop.

I hope that this provides some value to you in helping you to improve the photos.
