This is a shot of Sylph Sia, an international model. Shot completely in natural light with an old M9 Monochrom with a 90mm f2 submicron. 90mm is a tough nut to focus on an older rangefinder, but in natural light (in this case from a window) it renders amazing images. Combined with the CCD sensor of the old M9M, the result is hard to replicate with a modern camera/lens combo (sadly, I sold both). Simply edited in LR with tonal and brightness adjustments.
