It could be just a high contrast photograph. I know that at some point they used to wait for all the vectors to be drawn on a CRT with a "permanent"-resettable phosphor and then take a photo with everything on it, clear the screen, and start drawing the next frame. Fun stuff.
- bb88 5y agoYour thought intrigued me and I wanted to look further. https://piratefsh.github.io/2019/01/07/computer-art-history-part-1.html https://piratefsh.github.io/2019/01/07/computer-art-history-... https://piratefsh.github.io/2019/01/07/computer-art-history-part-2.html https://piratefsh.github.io/2019/01/07/computer-art-history-... So there were plotters, which would need to be photographed, like you were talking about, but there's also this: > And then they were the electronic or microfilm plotters. It works in a similar way as the mechanical plotter, but instead of a pen, it uses an electron beam and instead of paper, it “draws” on microfilm. The idea is that it plots an electron beam in a cathode ray tube, runs it through a camera lens system, which records these beams onto microfilm. I think of it like how a CRT display works, but it also exposes light onto film. The microfilm can then be viewed via a microfilm reader, printed or even animated."
