Thanks, Pete. You'll know the experience to be had when shooting with the M9 Monochrom, in that it is best to underexpose so that you don't lose detail in the treble (I think in musical analogies) and there is tons of detail to be had in the mids and bass. The screen on the back is so useless by modern standards, most of these shots, save the first, were pretty much completely black, with a little bit of light seeping through. But when you open them up in Lightroom, they look fantastic, and it's easy to draw out as much detail in the bass register as you want. You just have to trust the camera - a bit like shooting film.
There's a bit of flare in the path shot, but it was there to be seen, and I like it.
