This film can be seen as being Ilfords requivalent to Kodak Tri-X in being a film that is aimed towards documentary photography. As such it is a bit more grainy then FP4+, I've even seen it described as "seventies Tri-X" (I have no idea where, though), howver esepcially in medium format it looks very pleasing.
