was looking at some old photos of Kate bush, Stevie Nicks, and some other celebrities photoshoots from that time period and admiring the glowy affect or the purple and red colour palette on the photos wondering how I can achieve that same effect and then I realized that they did not have online editing software or even internet but the photos still look very nice and not like raw images I usually see. This may be a dumb question, I am not a photographer and do not know much about all this stuff but I am just curious.
I’m surprised nobody has explicitly mentioned this to you — they weren’t shooting on digital cameras, as they didn’t exist (or were in their early early stages of development). Pros didn’t start making the switch to digital from analogue (film) until the 2000s, and some still use film as well.
