Look folks, I can't hold a gun at your head and FORCE you to get the first
free introductory issue of The World Journal of Post-Factory Photography,
but I promised not to be like Luis and just say "read my book." So I'll
quote a few items WITH the page numbers.
First, there's an entire 3-part article about use of the step wedge, for
making enlarged negatives, for matching the negative to the emulsion
paper/ combination, and for reading step prints so you don't have to make
test prints for each negative -- pages 33 to 41.
There are several clear and distinct (also good-looking) schematics of
step prints with explanations of exactly how to read them, examples of how
different types of exposures will display (page 35), a chart on how to use
your step print instead of a densitometer (page 39), plus scans of actual
step prints showing the kinds of fine readings you can get from them (page
40 and 41).
There are examples of the various styles and sizes of step wedges
throughout the article, (I mean the whole thing is a positive HYMN to the
step wedge) with a rundown on the types made by Stouffer and Kodak at
prices from $5.40 to $180, depending on size & whether or not calibrated
There is also the information (page 37) that "I use the Stouffer Company's
T2115," a description of its adorable nature and the fact that it "costs
$5.50 cents plus postage with a discount for bulk orders to schools (see
Sources)." In that, by the way, I made a careless mistake (the only one
in the issue, guaranteed) because the actual price is $5.40 each plus
shipping. I also point out that for our purposes, and the tolerances we
work at, calibrated wedges are totally beside the point (page 38).
But I advise against getting only one, which gets lonely and wanders off
just when you need it most. You can never, in fact have too many -- I
often use 26 at a time to test two variations of emulsion on 13 papers. In
effect, for just one exposure you get a heap of information. As for
producing one yourself, don't bother. As I say on page 34, "The
manufacturers of step guides have devised ways to go from film base to
D-max in equal steps, but we in the real world have not." I believe some
folks like David Fokos have devised ways to approximate equal density with
digital ramps, but I believe that is also the advanced class -- and
specific to digital negatives.
In case you're wondering, BTW, I do not own stock in Stouffers, they do
not give me a special price (tho I've ordered hundreds on school
stationery at the educational discount for classes), and Dwight
Shackleford is a real person, not a construct of my diabolical marketing
Finally,in section 9 of Post-Factory's four pages of Sources and Services,
"Photo Equipment and Supplies" (page 46), is Stouffer Graphic Arts Equip't
Co, 1801 Commerce Dr., South Bend, Ind, 46628, 219/234-5023, fax
219/232-7989 or www.stouffer.net. Here I do note the price correctly, at
$5.40 each, and add that Stouffer sells "other resolution guides, gray
scales, scanner scales, etc."
cheers, and thanks for asking, Dwight,
