Here's a stupid question (showing my inexperience) - what did photographers do about white balance before digital?
What I did was I chose my film balance. You can get rolls of daylight or tungsten balanced film. Then you put color correction filters infront of the lens and on your lights if needed. For example, if I had tungsten balanced film loaded and the action moved outside before the film roll was done, I'd meter the scene, overexpose by 2/3 stops, then slap an 85B filter on (if my memory serves me correctly) to shift the daylight to be balanced with my film.
Or if I had daylight balanced film, and the light indoors was a mix of window light and tungsten, and it seemed the light was in the 4000K ballpark, I'd throw on an 80D filter (and compensate the exposure of course).
Or I'd use daylight film indoors and severely overpower the tungsten light with flash and use slaves to light the room up again. You needed a lot of flash power to do this though, as my film camera had a max sync speed of 1/60. Today, 1/250 is the norm.
So you see, using K is about ten billion times easier than balancing on film. I find K is a blessing with how easy it is to set. I sold my kodak wratten filter set and was very happy to see it go!
