If only there were a reliable source of frozen Plus-X in
4x5 and 120. It
was a worthy competitor to my beloved APX 100.
If you have a sample you can tell from the
perforations. Plus-X still
film has Kodak Standard perfs (oblong) and Plus-X motion
picture
negative has Bell & Howell perfs (round sides).
Plus-X film in 35mm format was a pretty good film. But
4147 Plus-X in
sheet sizes was so different it should have had a
different name
altogether. It was all toe, and the way I use film, I hate
that as it
lowers the shadow contrast way too much for my taste. I
really liked the
TMX film and TMY as they had shorter toes. But some people
had a lot of
trouble with short-toe films.
YMMV.
The very long toe films seem to have been a Kodak
specialty. Plus-X Pan sheet film had a characteristic curve
without any straight line section at all and Tri-X Pan sheet
film was very nearly the same. I have no idea why Kodak
made the stuff but they seem to have sold a lot. If you use
it correctly you can get very dramatic effects with very
bright highlights but its not good for general purpose
photography. Kodak made the same stuff as roll film but also
made a medium toe conventional film as roll film also called
Plus-X. I think Kodak had certain brand names they thought
were prestigeous and used them for several different
products. An example if Ektar, used originally as a name of
a lens and later as the name of a color film.
Old Kodak film names are interesting, there was SS Pan
for Super Sensitive Pan, also Background-X a very slow
motion picture stock made for special effects but often used
for general photography because of its very fine grain.
Background-X was the predecessor of Panatomic-X. Kodak used
to advertise in the motion picture photographer's magazines
"No Superior" "Superior" being the brand name of DuPont's
motion picture (and still) stock.
