What do you use this for ? I can't really see the necessity for a B&W
tranparency film. Do people still do "slide shows" ?
Yes. I'm one of them.
They can also be printed if the lab used knows how to do it, although it's
obviously not the same as printing from B/W negative. If properly
conducted, with a good projector *lens* and white matte screen, large
screen projection has a "WOW" factor. Too many people are accustomed to
the relatively low resolution of television and their computer
monitors. The ISO 25 to 100, and a couple 160 (tungsten) and 200 chromes
can fill a wall with dramatically higher resolution images.
I not only have an Ektagraphic 2 (previous generation built like a tank)
for 35mm projection, but a "dual format" that can handle 5x5 (35mm) or 7x7
(medium format) that's used for projecting 645 transparencies. The screen
is 50 X 50 inches. Projecting slow medium format chromes has an additional
"**WOW**" factor. Showing them just *before* the 35mm slides is *not*
recommended (3mm slide frames are also recommended to prevent projector
jamming).
The "art" of giving a slide show is most important to keep from boring
people to sleep. I use several basic rules:
(a) Each slide must have some relevance to the great majority of
viewers: whether they're in it, some they know well is in it, is about an
event they attended, is of a locale they're familiar with, is about
something in which they have a strong interest, etc.
(b) Slides are ruthlessly edited before going into a tray (see "d" about
storage): no repetition using multiple slides of essentially the same
thing is allowed. Slides are stored in archival pages in binders, not in
trays. Trays are used only for presentation. The pages go onto a light
table for the "first cut" and it's edited downward at least once more (see
"e"). The *only* exception is when it's for a few people to ask for an
opinion about which one they like better, and that is quite rare.
(c) No more than about 30-45 minutes for a show. No more than one slide
tray (or the equivalent of a full one if it's dual format). Dwell time is
shortened if the slide count goes up beyond about 50-60 slides.
(d) Presentation sequence is set up in a logical order to tell a story, or
a series of shorter stories, even if they're not chronological, or in
sequence within a single roll. Since both of my projectors go "black
screen" with a blank slot, they're used as natural divisions within a
single show. The workaround, if a projector doesn't do this, is using
unexposed 37th frames that come back.
(e) A show has a "dress rehearsal" before anyone else sees it. This has
prevented upside down, sideways and backwards slides more times than I care
to remember.
The portfolio used to "land" the gallery exhibit this Fall was all done
with transparency in a slide tray; about 40 total.
