    I bought a few 35mm rolls of Ilford PAN 100 recently in India. The
    speed specified is ASA 100.

    I developed the roll and like the results very much. However the edge
    marking clearly says "Ilford HP5 Plus". Also there is a number, I
    think it is: 4307.

    On the web I find that Ilford HP5 Plus is a 400 speed film!

    So I would like to know more about this. What is the real speed of
    this Ilford PAN 100? Can anyone please help?

  2. I think you've caught Ilford in a curious labeling mistake!

    HP5 Plus is of course a 400 speed film. It has enough exposure latitude
    that if exposed at 100, it will produce pictures, especially if not

  3. It's probably not a mistake. It's more of what is now called a "re-tasking".
    Remember this was from India, a country where people parking their
    Mercedes' have to be careful not to run over the people sleeping in the
    street who got there first.

    Monochrome photography still makes economic sense especialy with cheap
    fixed focus and exposure point and shoot cameras. By exposing HP5 plus
    at ISO 100 and reducing development you can get good negatives.

    The same thing is done here with ISO 200 color negative film.

    I think color works better in bad cameras. It makes
    up for lack of contrast and a fuzzy lens, and the exposure
    latitude of color is pretty huge.

    Color also works better with every day subjects. Oh Wow! color can
    be had for a few colored balloons and a blue sky, making up
    for so-what subject matter, composition and lighting.

    Old black & white snapshots are uniformly dull: grey on grey or soot
    on chalk, no texture, white or grey skies: It was as if everyone
    lived in East Berlin before it was colorized.

    So what does this mean? I would be delighted to have a real 400 speed
    film. That gives me flexibility in exposure especiall in low light
    using colour filters.

    Or is it possible that this is 400 speed film that somehow failed to
    meet the quality standards, and hence had to be degraded?

  6. That is possible. Another possibility is that a batch of 100-speed film was
    mistakenly edge-labeled with the wrong labeling at the factory -- and no one
    would notice until it was developed.

    Or they did notice and that's why it was packaged Pan 100. Instead of
    tossing otherwise good film they sent it out in a budget package.

    Thanks for all the responses. I will try to expose one roll at 400 ASA
    to see if this can work satisfactorily at that speed.

    Ilford PAN 100 is not HP5. It's a 100 ASA film. You can get the specs from
    the Ilford site. There is a Ilford PAN 400 also.

    And in India, B&W photography is costlier than color photography. It's not
    that different from US.
