| One of the never-ending
fascinations of darkroom work is the way in which you can manipulate your
images. Two effects in particular, softening and vignetting, can give
you lovely, vintage looking pictures with a minimum of effort. Both tend
to work best with black and white, though they can be equally applicable
to color.
Softening can be desirable
for a number of reasons. The most common is to give the print a romantic,
dreamy quality. The accompanying illustration of Sophie in a flying helmet
is a good example. In the straight print the edges are hard and the picture
is very literal. In the softened shot you can imagine a young girl dreaming
of being the next Amelia Earhart.
Softening has other uses, too.
Sophie was 14 or 15 when we shot that, but the same technique can help
to flatter older, more time-worn skin. It makes wrinkles appear less deep,
and smoothes the skin texture which makes it look younger. Even blemishes,
freckles, and liver spots become less obvious.
Softening is easy: hold a diffuser
under the lens during the printing exposure. It is important to realize,
though, that diffusion between the lens and the print does not replace
a soft-focus lens at the taking stage. It doesn't do the same thing at
all. With a soft-focus lens, spherical aberration in the lens allows a
sharp image, but with highlights that seem to spread and glow. Adding
diffusion at the enlarging stage simply softens edges and textures, but
in effect, it spreads the shadows out, not the highlights, so the characteristic
soft-focus glow is missing; unless, of course, you are using pos/pos printing,
such as Ilfochrome Classic from transparencies.
You can experiment with various
materials, but a traditional diffuser is a nylon stocking stretched over
a wire frame. For the diffused pictures which accompany this article I
used an old wire coat hanger, covered with a black knee-high nylon stocking.
The advantage of the knee-high (or even ankle high) stocking is that you
don't have to cut it down. Cutting means that there is a risk of runs
or "ladders" and therefore uneven diffusion.
The actual shape of the diffuser
is not critical, but the material has to be tightly stretched with no
wrinkles. The easiest way to get a nice, even diffusion is to make the
frame somewhat larger than the lens so any wrinkles or denser areas can
be kept well away from the lens. I bent the coat hanger into a lollipop
shape with a diameter of about 6" and a handle. I then stretched the stocking
over it, taking up the slack at one end with a knot, and using the slack
at the other end to cushion the handle.
The color of the diffuser will
influence both exposure and contrast. I find that if I use a black nylon
stocking stretched over the wire frame, I generally have to give the print
up to 11/2 stops extra exposure and up to a full grade of extra contrast.
I have experimented with a double layer of white net, too, and in that
case both the exposure and the contrast needed less adjustment: about
1/4 to 1/2 stop more exposure and up to 1/2 grade more contrast. The fastest
way to determine exposure and contrast is first to do four or five tests
on the same strip, at 1/2 stop increments. When you have the best exposure,
you can do another test strip for contrast. Usually, trying three full
grades (one at the same grade as the undiffused work print, plus one at
a grade harder and another at two grades harder) will give you all the
information you need to determine the best contrast.
Vignettes
There are four basic types of vignette: soft-edged white, hard-edged white,
soft-edged black, and hard-edged black. All make use of masks. For a white
vignette you mask the area around the subject. For a black vignette you
mask the subject. Another way of vignetting is to sandwich a vignetting
screen with your negative, but that is another story.
There are vignetting tools
available that fit under the enlarger lens, but beware: they don't all
fit onto every enlarger. I have one set that I have been trying to adapt
to my enlargers for years, and I still can't figure out how, even with
a special adapter provided by the manufacturer.
Hard-edge vignettes require
masks which are precision cut and held down firmly to prevent light leaks.
If you have a metal easel and magnetic strips this is fairly easy. Otherwise,
soft-edged vignettes are easier to deal with and require less precision
in both cutting and printing. I think they look better, too. Some people
simply use their hands to mask the background, but I find this is not
as reliable as a mask. The illustrations accompanying the article are
all soft-edge vignettes.
To get started, you need to
cut a mask. It can be any shape you like. Oval masks are very traditional,
fairly simple to cut, and easy to work with.
Correct sizing of the mask
is crucial. The background determines this, to some extent. Although you
can use vignetting to eliminate unwanted backgrounds, the easiest pictures
to vignette are ones which have a plain (or at least unobtrusive) light
background.
First, project the image you
will be vignetting onto the baseboard. The mask for a white vignette around
the subject needs to have an aperture that is smaller than the subject
area by perhaps 25-30 percent. If you make the mask from stiff card then
you can hold it by the edge, as shown in the illustration. Black construction
paper works well, too, but it may need to be supported. I often tape a
mask made of construction paper to the same wire frame I use for softening.
Once you have determined the correct exposure for the subject, make a
print using the mask. To get soft, fading edges, keep the mask moving
up and down, parallel with the light beam. Alternatively, use a gentle
circular motion at right angles to the light beam. The movement does not
have to be great. Don't be discouraged if you don't get it right the first
time. You may need to adjust the size of the mask to make the vignette
larger or smaller, or you may only need to hold the mask higher or lower.
It is simply a matter of practice.
Black vignettes are much more
difficult and seldom look as good as white ones. The technique involves
masking the subject, then overexposing the background around it. The center
that was cut out to make the aperture for a white vignette can be used
for making black vignettes, or you can cut a new mask. The main thing
to remember is that this time the mask will need to be somewhat larger
than you might expect because light has a habit of creeping in around
the edges of the mask and fogging the image. Again, you may need to make
adjustments to the size of your mask when you start printing.
A firm wire or a piece of thin,
but firm, flexible plastic is needed to hold the mask. This handle must
move during the exposure, otherwise you can get a light streak on the
print.
Two exposures are required
for a black vignette. The first exposure gives you the image. The second
exposure can be a white-light exposure with no negative in the carrier,
or you can use a diffuser--usually a piece of translucent plastic--under
the lens. With a white-light exposure you will need to stop the lens down
as far as it will go and keep the exposure brief. If you go for the other
option you need to be able to swing the plastic in below the lens as you
would a red filter.
Before you start printing black
vignettes it is a good idea to take your mask in hand and do a dry run.
Project the image on the baseboard and practice masking it. Remember,
you won't be able to see it when you are making the second exposure, so
it is important to memorize where you want the mask to be when you start
printing for real.
To make up for any fogging
during the vignetting exposure, print a little lighter and with somewhat
more contrast than usual. The adjustments will depend on the image you
are printing. To soften the edges of any vignette even more, you can glue
a small amount of white cotton to the edges of the mask. You don't need
very much.
Because of their "vintage"
connotations, vignetted prints (especially white vignettes) often look
good when toned--usually sepia--and they can take very well to handcoloring.
You can go for a naturalistic color, or you can just color parts of the
image: in a portrait the eyes, maybe, or the lips, or in a street scene,
just one automobile. And, of course, you can use everything together for
really old-fashioned pictures: softening, vignetting, toning, and handcoloring.
Try it!
