Reply to comment by canigetahoohelp in Whoever first observed the red-eyes camera flash effect must have thought the subject of the photo was possessed or something. by StaleTheBread

Oh wow! I always thought it was something to do with cameras picking up light in a different way than we do. But I guess I was mixing up film cameras with cheap digital cameras that don’t filter IR.

I guess it has something to do with the angle of the flash and how we don’t usually see each others eyes at the right angle and lighting for something like that.

Edit: thank you for answering my question. Other people on here don’t seem to have much patience

I was told its because the flash bounces off the back of our eyes back into the camera, cameras with an anti red eye shines a light into your eye before the flash so your eyes contract in reaction and so less likely for the flash to bounce out compared to if they were dilated

Wow, that’s really interesting! And we don’t usually look at people getting light shined right into their eyes so we rarely see it outside of photos

Yeah no problem! I see you’re getting downvoted for asking the question… sometimes human beings don’t know things until they ask. Happy to share some insight! It’s definitely the angle of the light/flash.

Thanks! I wish people actually read the comments before posting. Then they’d know plenty of people already corrected me

Edit: also I wish people wouldn’t take me so literally. I’m not trying to say early photographers were cowering in fear at the thought of demons.

And on top of that, even if the literal “first” people to see it knew, it doesn’t mean they knew to inform consumers. They may have though, “eh, they’ll be smart enough to not freak out” and then maybe consumers freaked out.
