Re: 70s Look in Apple Color

Cameras prior to about 1984 were based on tube technology; vidicons, plumbicons, saticon, and so on. Recordings were also nearly 100% tape based - ranging from 2" quad to 3/4 Umatic and some portable C-format 1" which all eventually gave way to 1/2" Betacam CAV - type, but that didn't really get going before CCD solid state imaging started to get some traction.

So, if there was a way to simulate video shot in the seventies, it would be Standard Def for starters, 4:3 aspect ratio, and exhibit tube smear, bloom, prism-split longitudinal aberration, possibly back-focus differences between channels R,G,B, burn-in trail, noisy and soft blues, and all the baseband composite frequency response defects, crosstalk, DG, and DP ( I guess I could elaborate Differential Gain and Phase but it seems like overkill), and all the other stuff we no longer think about that were killers in analog compsite. Of course, people routinely ignored scopes back in those days anyway, just like today, or just can't read them at all which is more widespread than ever now, so even when exposure, filtering, and everything else was great and would likely be indistinguishable from anything shot today, redubs and transfers would be screwed up (plus ca change, right?). So phase, saturation and gain errors would be perfectly normal from those times.

You might also be thinking about prime time film, which would have all been telecined to video using very similar technology, especially the RCA-type TK film chains , which were simply 3-tube static-mounted cameras aimed at a shutter-interrupt. We didn't really worry too much about 2:3 pulldown, since that was pretty much lost in the afterimage defects, anyway. For a 70's film transfer look, I'd go for a ton of contrast, since most stocks were low-speed in those days and were either reversal or printed for telecine, since no one in their right mind would ever load neg on a telecine.
