Wait, do digital cameras not do the red eye effect? Now that I think about it, I don’t think I’ve seen a photo with red eye in it in a long time, but I had always assumed that was a consequence of the camera flash, not the film…
Oh god , remember the anti red eye flash that strobed for a second before the flash?
I still don’t understand how that worked. At the time I thought it was “getting your eyes used to the bright light so they wouldn’t turn red with the big flash,” but that definitely doesn’t make sense.

I understood it as the red eyes you see in photos is the wide open iris of an eye you’re photographing zooming in on the blood vessels in the back of the eye. Flashing bright light before the photo makes the iris of the person you’re photographing contract significantly, so you can’t see the blood vessels in the back of the eye anymore.
Hardly anyone takes photos with a flash anymore.
Phones instead crank up the sensitivity and use AI to get rid of the noise (=draw an image that vaguely resembles what’s in front of the camera).
The sensors themselves are also slightly better than 20 years ago, much less 40. Meaning they can probably produce a nicer image before all the AI shit.

It was the flash. That’s why cameras flash earlier now.

So I was right??!!
Yes
With film cameras, you got me. No clue. I always wondered though.
Well, that’s it. A first (few) flash(es) to contract your retina, and then the flash to take the picture.

I distinctly remember early Facebook and its predecessors being filled with red-eye pictures
