@42andcounting I remember in childhood not quite making the connection between a camera being used, and the resulting photo. I thought photos in albums "just happened". All I knew was that we had to stand and smile when someone used a camera, and possibly be dazzled by the flash. When my teacher used a Polaroid camera, and you saw the photo straight away, that made much more sense. Mind you, lots of teenagers now would be amazed to see one of those.
@ContessaferJones I've just had to look up what a "trunk call" was.
Did they really have to be booked? "Trunk" is a funny word when it doesn't mean part of an elephant, or a tree trunk. It has lots of old-fashioned uses, such as a trunk for luggage (although perhaps Harry Potter has made this more well-known), trunk road, and when "trunk" means the upper body.
@teaandcustardcreamsx With the Lion, the Witch and the Wardrobe, were you referring to the BBC serial of it from the 1980s, or was there an earlier movie?
See the picture for more old photo technology: who remembers those, and having to put the slides (transparencies if you were posh) in upside down, and the right way round? It was really weird if you got that wrong, and you saw a photo of a familiar place being reversed like that. My grandmother, a keen photographer, did not use printed photos at all: she only ever used slides. She had a slide projector and screen, and also a much smaller tabletop device for looking at slides.
