Recreating the same exact lighting WAY after the fact, can be a daunting task if one is not prepared. Getting this portrait to look similar to the original ones taken so long ago was key.
Luckily, I take extensive setup notes and draw cryptic diagrams for this very situation. Without my detailed information, I would not be able to duplicate the shot, and I would have to try to "fix it" in photoshop... not a good strategy.
With my notes in hand, everything worked like a charm.
