The
following piece was written before I switched completely to
digital, it still applies to film. With a digital camera you
can set the white balance to match lighting conditions. I
now use $17 quartz work lights bought at Canadian Tire rather
than $300 photo lamps and get just as good results. While
digital isn't quite as sharp as film it is much more versatile.
I send image files (usually jpeg) by email to magazines, galleries
and competitions. I use them to keep my website up-to-date.
I have had them published in books. I also use them in exhibition
catalogues that I design and layout using Adobe CS In Design
(formerly Page Maker). I burn a CD and send it to a digital
print service who prints and assembles catalogues for the
gallery involved. The switch to digital images from film is
inevitable for this kind of work sooner or later. I love knowing
that I've got a good shot while the piece is still in the
studio rather than wait for film to come back.
I use a SLR (single lense reflex) digital camera with high
quality interchangeable lenses. Using a professional level
lense really helps to make a good image.
That said, if you do use film this is my advice:
It is important to use "tungsten"
type film with these quatrz lights. Normal daylight film won't
give you accurate colours. It is also important to remove
any lens filters such as UV or Daylight filters which are
often on lenses to protect them from scratches. Filters can
give a pinkish cast to your slides. I use Kodak Ektachrome
160T(tungsten) EPT 135-36.
I have rigged
a white-painted piece of light plyboard over my setup to reflect
the quartz light down on the piece (as pictured). This is
on rails and can be tilted and raised to get the best effect.
The paper loop runs from high on the wall behind the setup
area down over a work table and drapes down the front of the
table giving a graded seemless surface. The lights are aimed
up at the reflective plyboard to give a nice general diffuse
light that leaves no "hot spots" or reflections.
Be careful with the lights. They are very hot and can cause
burns or start a fire if left too close to anything flammable.
Be sure that all other light sources in the room are turned
off and that there is little or no sunlight penetrating the
room. My setup is in a cellar room. Before I had a dedicated
room for this I did my shooting after dark in the studio so
I wouldn't have to deal with blocking off the light from windows.
Shooting. Once you are set up and the camera
is ready, you want shots that show your work to its best advantage.
(That means keep the cracks and glaze flaws turned away from
the camera). It also means focus and framing are important
as well as a simple, undistracting background. Don't leave
too much space around the piece but enough so it doesn't crowd
the edges of the slide. It is generally a good rule of thumb
to adjust the f-stop (look it up or ask a friend) on the lens
to its mid-range. I like 11 to 16. This gives good depth-of-field
without sacrificing definition.
Bracketing:
Once you have composed your shot and are happy
with the lighting, you need to be sure that the lens is focussed
(choose a spot midway between the front of the piece and the
furthest part visible toward the back of the piece to focus
on). Now adjust your lens speed to give you a normal exposure
at the f-stop you've selected.
What you want to do at this point is shoot
several exposures in "half-stops" above and below
what the meter wants you to do, as well as "on-meter".
I generally find I get my best shots 1/2 to 1 full stop below
what the meter calls for. Many electronic cameras have a meter
over-ride that allows you to adjust the exposure in 1/2 stops
without actually changing the speed manually, but don't worry,
if your camera doesn't have that feature just adjust the shutter
speed or the apperature to over and under expose your shots.
As you get to know your setup and film you can narrow down
the range of your bracketing, to start with it's better to
have the range wide to be sure that you get good exposures.
I also use the timing device on the camera to trigger the
shutter to avoid jiggling the camera when pushing the shutter.
This also pre-releases the mirror in the camera so it doesn't
add any vibration during the exposure.
In-Camera Dupes:
I take several extra exposures at the settings
I think will be right to make "in-camera dupes".
That means when my slides come back from the processor I have
a set of duplicates all ready to use. Aside from being cheaper
than getting slides duplicated they are also sharper and have
better colour balance. They are, in fact, originals. That
means they will be suitable for reproduction in magazines
and will be better representatives of your work than duplicates.
Conclusion:
Good images are an essential for pretty well
all competitions, grant applications and publications. It
may be an aggravation to have to deal with them, but my take
is that since it can't be avoided it might as well be done
well and as easily and cheaply as possible. It took me years
to figure this out, I just wish I had gotten down to it sooner
than I did. It really isn't as hard as it might seem. If you
have a group of friends or a guild, it might be worth looking
into setting up a "photo coop" so that you can all
use the same pooled euipment and shared know-how to deal with
this effectively and cheaply.
