Push/pull, plus/minus development?
The contrast range of chromes is easily adjustable in development. The practice and principle here is classic zone system, simply developing for a specific final result. It is no stretch to factor the effects of the lens into this.
Where we place our subjects on the curve, including our black point, is a choice not a given.
Popping in a bit of flash on a subject allows us to reduce exposure settings overall, darkening the background as much as we please.
Creative use of flare?
By protecting or exposing the lens to stray light.
My point is simply that it is rare in photography not to have options for controlling our results.
