    FP4 and FP4+

    Was there a difference between FP4 and FP4+ and HP5 and HP5+? Or was this a marketing invention to try and convince people that they have produced something new and better?

    The films were improved, the knock on effect of advances in the control of emulsion making, however the change wasn't as significant as say FP3 to FP4.

    Improved in what way for the photographer?

    llford reflect changes in the name something Kodak never did with Plus X, & Tri-X in 74/5 years.

    Films improve, it's what we want & need.

    I wonder if the marketing ploy was actually to under sell these a little? They maybe should have called them FP5 and HP6, but perhaps used the 'plus' as a way of suggesting an upgrade rather than a new emulsion, so as not to steal the thunder of the launch of the Delta series a short time afterwards? Just me speculatin'

    Thanks for this, but if you never push or pull, I can't find anywhere in that text what the difference is to exposure/development by the photographer, or reference to FP4 and FP4+. Sorry to be pedantic but I never noticed any difference.

    Well if you never noticed a difference it's too late to ask over 20 years later

    There's more important issues these days.

    I am shooting both FP4 and FP4+ regularly and I can't tell the difference to be honest.
