    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…

    Edit: TIL that camera redeye does come from the flash, but it hasn’t been much of a thing these days because today’s phones/cameras adjust the flash timing to compensate. Thanks for the replies!

        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.

        Now that you mention it, I think you might be right… My memory’s not the best lol. From the other replies, it seems that the rarity of redeye these days comes from the timing of modern cameras’ flash, not whether or not it uses film.
