in Japan and the USA...
1. what were major camera brand names and/or types from about 1965-1975?
2. common film speeds then?
3. color? black and white? which was more common to the public?
4. instant cameras (like Polaroids)? did they exist then?
i basically need this for a character who was born in the US but is half Japanese, and she is living in Japan when she is about 10 years old, which would be sometime during the above time span. she has photographs of herself and another character in my fic, and i want to know if it's plausible that it was an instant camera and whether or not it would be in color yet.
