Revisited this topic, and have to conclude that Real life situations always tell me and most of the others the most, in that regard ‘ Dynamic range’ is more or less a conceptual technical term and ‘latitude’ an empirical more practical way to talk about this. I was just standing at station Sloterdijk in Amsterdam on the lowest deck, which is a dark alley /corridor. about 350m up in length, with a few open gaps from left and right, just enough for a tiny bit of fill. 
The lights are old fluorescents balanced at around 3000 kelvin, and over day they almost have zero effect other then a tiny bit of orange glow and a bit of vibe. Sun was harsh and out in my direction, and I was waiting for my train, and I try to study light whenever I can see, why it has a certain quality, and I always try to bring a camera, even though it might give me a hernia some day. Even though I knew the camera would succeed I wanted to see what the camera would do with this light situation. basically not a lot of mids, but a bright outside with the sky and the white stones, and inside a bounced grey environment with a few incandescent bulbs. My eyes tend to have to focus either to the outside to avoid clipping that or, open up for the inside which is dark and non contrasty. If a camera can capture this, and still have enough latitude to open up for different grades, I would be a happy man, because I tend not to be willing to capture stuff that’s unpleasent to my eyes, Because everything starts with the eye! Any way I should stop talking, Here are a few images and I included a dropbox link to a somewhat uncompressed DRX, please note that this is not a detail test, this was shot with a tiny mamiya sekor 58mm 135 lens, and an aivascope 1.5X anamorphic adapter.
