Night Photography

I have read many posts regarding taking night time photography and I am a little bemuddled as to why you would want to use 400 ISO film. For starters, you will require to use a tripod for anything over 1/30 sec so therefore if you had to shoot at 4secs on 400 ISO film then that equates to only 16 seconds on 100 ISO. Plus you get the much better grain size , so that if you took a pearler of a photo and you wanted to enlarge it, the grainier film ie 400 ISO would fall apart much more sooner than 100 ISO. As with a comment I read about repricocity, true that does happen, however, as in most cases, most film is shot on a daylight based film and the night lighting, whether it be Tungstein or other, will give a reddish caste. Therefore colour shifts in the emolsion are nullified by the colour discrepancies in the existing light source. If you want proof of this, just look at any photo of a Fluro tube (not corrected to daylight light) and it will appear green. And as a last resort, no matter how many photos you take, each processing lab produces different results anyway. I have lost count of crap prints from one lab that gave inconsistent results depending on which film based emulsion I was using at the time. Mostly I ended up with magenta prints but with fujicolour, not only was I ending up with Cyan prints but generally about 1 stop lighter as well ( and no it was not an incorrect camera setting-just an inability for the processor to correctly read the density of the emulsion). So to sum it up, the slower the ISO the better the quality, and if concerned about colour reciprocity, then use filters :-)
