Film: Light hits chemicals, chemicals react, more chemicals used to convert the emulsion into image.
Digital: light hits sensor, sensor converts light to electricity, processors used to convert electricity into image.
Electronic stuff comes from shops (not factories) - just like milk comes from supermarkets (not cows). Modern life, where the item is shipped a long way to the shop disconnects perception of the thing and its origin. Also a reason why most young people in richer countries do not want to qualify to design, develop and produce these products on which our life style depends. A serious issue for our ability to sustain technological advance when most of the production is done by contractors to OEMs and innovation is done by the old and experienced in another country - but where do we get the flow of old and experienced staff from.
I remember seeing darkrooms when I was you - set up in temporary places such as at a primary school camp - so I got the idea of the process and listened enough in chemistry to know what it was about - then tried myself. It was helpful to have an old school mate who was enthusiastic who also taught me a bit. He was the Rhodes Scholar in my year. Made me look mediocre at school - someone else was top of the state in our year at school.
