Those sliders in developing software can turn a young person old or turn a new photo into an old photo, visually speaking.
A photographer can do so much more with any given photo today than when I was shooting film that I don't think you could accurately put a numerical value on the change, such as, "We can to 200% more with a photo today." The method is completely different and the key fact is that you can always go back and start over. Adobe likes to say that their tools are "non-destructive" but you never destroy your original unless you delete it or save something with exactly the same name in exactly the same location.
This video is just me having fun to provide some examples. I've used the sliders in Adobe Lightroom Classic and those in an adjustment brush to make changes that I really hope this lovely lady never sees.
