The only one I used is the NPH. It's a 400 ISO film that's pretty lower
contrast and saturation compared to the amateur films. I used this film a
lot for portraits in available light, with a 85mm open at 1.8 most of the
time. It is perfect for getting smooth, natural skin tones. It is pretty
fine grained as well. It is one of the favourite films of wedding
photographers. It used to be pretty inexpensive for a pro film (haven't
bought any for some time now).
However, I once finished a NPH roll shooting some landscapes and did not
like the results at all: the results lacked... contrast and saturation (IMO
at least). I think the Reala is more all-round, but lacks the speed for
available light portraits.
The NPS is close to NPH in terms of tones and contrast but is 160 ISO only.
The NPC is 160 ISO as well but is supposed to have slightly higher contrast
and color saturation.
A comparison of the NPC, NPS and Reala can be found at
The NPZ is very different: it is a 800 ISO film for press photographers.
