For as long as I can remember, I've always thought "on camera" interviews were always done with the subject being interviewed in front of a green screen. After learning more about video production, I've realized that some have been in natural environments with "depth of field" taking part in the interviewed subjects background/backdrop looking so out of focus and unnatural --from what I could see-- and black screen with the subject illuminated or white screen that's illuminated. When do you use which? Is it just personal preference? When is it better to use either of them? What would a "keyed" black background/white background look like using green screen? Identical to authentic black screen or white screen being used? Have you ever used any of them for "on camera" interviews? For anything? What do you use the most for "on camera" interviews? The Least?
This for example I thought was green screen:
