We’ve all been there before. You take a really nice group photo, look at it, and everyone looks like a demonic dragon with red eyes.
Nowadays there are plenty of fancy editing apps to fix it, but why does it happen in the first place?!
When you take the photo the camera’s flash sends a lot of light into the eye in a very short amount of time. The light is then reflected off the back of the eye and out through the pupil. Now because the camera lens is so close to the flash so the camera can capture images very quickly it catches the light reflecting back out.
By now you’re asking… then why is it actually RED?!
This is because the interior surface of the eye which includes the retina has something called Melanin. A pigment that gives it a brownish-reddish color.
