I remember seeing a discussion in here about reciprocity behavior of many films. Unfortunately, I can not find the thread now.
But as far as I can remember, chromogenic films (XP2 and BW400) seem to respond quite well to long exposure with small correction. Plus you get their speed!
I have mainly used three films for night photography: Fuji Acros 100 has really excellent reciprocity, which makes it effectively faster than even ISO 800 films for long exposures (no correction required up to 2 min); Kodak TMax 3200 pushed to 6400, although very grainy as you can imagine, but capable of almost photographing the total darkness; Kodak Tri-X for good reciprocity characteristics and interesting highlight rendition.
Interesting discussion.
I have still two 120 rolls of Acros 100 lying around, so I will use one to make some night shots as a nice experiment (never done that).
What ISO do you use and how to develop it? Any recommendations?

Another thing: someone suggested overexposing and pulling: not good. Pulling means underdevelopment,
Why not? Underdevelopment and overexposure is basic sensitometry, and with a lot of the films, the ISO can range between a few stops given the right development and the right developer. It shouldn't be seen as underdevelopment if the correct type of film has been rated and exposed with this in mind. 'Expose for the shadows and develop for the highlights,' as we were taught ages ago! However, films like Acros, (I would think the tonality of Acros would be very mushy if pulled this way), TMX and possibly the Deltas would not react so well as Trix, HP5+ and FP4+. Reciprocity would also have to be considered, but it is amazing how smoother and more managable for printing the tonal range can become. However, this is if it is a scene with a high range of contrast. It's not always applicable, and certainly not recommended if it is low contrast.
Subject would be cityscapes, office buildings and maybe catch a train passing by.
