    Rather a lot, I cut my teeth on ex Government surplus bulk rolls of FP3 and HP3. These were quite soft emulsions very easy to get reticulation, but equivalent Kodak films of that era were no different in this respect.

    FP3 was OK, FP4 was much better, FP4+ is that slight step better.

    HP3 was a bit grainy, HP4 was slightly better, however HP5 was very much better in terms of grain and tonality many thought ahead of Tri-X at the time. Modern HP5+ is a superb film.

    How about Ilfolith IH4? I've got almost a full box of 4x5. I recall getting something from this film a few years ago, but I've forgotten exposures and processing details. (Ya, I know it's not for grey scale...)

    Cheers,

    Ansel Adams had the Zone System... I'm working on the points system. First I points it here, and then I points it there...

    Ilfolith is very old, it'll be slow and was designed to be processed in a lith developer, for best sharpness but a high contrast developer can be used as well, someting like 5 EI. I did use some Ilfolith way back.

    Ilford sold their Graphic Arts and Medical side to Agfa from memory sometime in the 1970's.

    They are definitely a little different. I still have some sheet of the original FP4 laying around. I liked the
    base a little better because it was not so slick, and less prone to Newton Rings, though the current version is not a serious offender in that respect. The changes to both FP4 and HP5 were subtle, but
    noticeable. Whether something is an impovement or not depends on what you are doing, what you are
    used to, etc. The change didn't personally cause me any problems, or really any fuss with procedure.

    Ian, interesting that you mention Ilford selling (possibly) their graphic arts film division to Agfa in the 70's. I have just checked in my darkroom.

    My last purchase of Ilford 30.5cmx45.7cm (12x18") News Dot x 100 sheets with the code of 171-0203 was made by me in the mid to late nineties in Melbourne Australia.

    With regard to Ilford naming their facility (I think that's what Simon means) "EP2" is fascinating for those of us who did colour printing using one of Kodak's colour processes and materials

    Mick.

    Mick, I can't remember the exact year but Ilford had sold the Medical/Graphics side before they moved to Mobberley closing their plants in the south. 1980 at the latest I think as it was a few years before the move.
