Very nice shot. Shooting during or after rain is often useful. I have no recipes for success, but a few hints:
- exposure compensation -2/3 (dusk), -1 (night with lots of lights), down to -3 EV if very dark scene, to avoid overexposure. The darkness is then fine-tuned in PP.
- shooting during or after rain is often a good idea
- apertures normally f/4, at times f/2.8, exceptionally f/2.0 or wider, to avoid nasty artefacts (blooming), possibly get sunstars (lens-dependent), and to 'forgive' focussing errors. Quality loss due to higher ISO is usually more than compensated by the better optical quality;
- FL typically 24 to 58mm; longer is seldom useful unless you got a tripod. Night shots are the sole circumstance where I like 35mm
- Flare-insensitive lenses are a plus; 24/3.5 PC-E is such a lens; Zeiss 35/2 is also excellent
- Auto ISO (Df: limit set to 12800; possibly 25600 if B&W is the goal)
- Composition: indeed, avoid pitch black skies eating the majority of the picture, otherwise no precautions
- The Tamron 45/1.8, which is stabilized, offers a range of possibilities because it allows sharp pics to be shot at 1/8s, or even 1/4s with some precautions.
- I never use tripods for night shots (when I am walking alone at night, I prefer not to be a standing target), but of course these will take you a step further
