Zenith film

[Telecolor 3007]

Let us not forget that back in the days it was easier to display moving images from an 16 m.m. film than from an electronic screen. Well, you could do videotaping and retroprojection, but for 30-40 shows around different areas it was easier to move around with an portable 16 m.m. movie projector. You could show it to people that didn't had a colour tv, you could show them to business.
Plus, films (even 16 m.m.) could offer a better images then a television camera and videotape back then. From a 16 m.m. you could get 720p... back then 720p was a far away dream on television.

But I wonder about the colours. They don't look so vivid. Or the film deteriorated due to it's age?
