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.
In addition to those options also mentioned here, there was excellent hair and makeup designed for still photography, finely tuned lighting from years of craft, and diffusion filters on the camera lens (of many varieties) to make the skin glow. Then in the b&w darkroom, more diffusion filters under the lens to make the darks glow, selective use of poly contrast filters, and print retouching. Color went out to the retoucher, too, and could be dyed. So, lots of things.
