The more I use Neopan 400 the more remarkable I think it is. I have done some testing with the 1600 sibling not having used it in my Leicas (I have used it some time back in my SLR) and was reminded of what an amazing 400+ speed film this is. It is nowere near 1600 at its natural speed, although I do find it gives a full stop more than the 400 (I rate them at 320 and 640 respectively). The 1600, downrated like this, in Xtol 1+2, gives a truly classic hard hitting monochrome reportage look. The grain is super crisp, the shadows are there and the highlights control beautifully if you develop modestly. I seriously recommend anyone looking for a touch more speed than their regular 400 film to look at this. It provides easily as much resolution as TriX, more speed and, well, I dont see the catch.
