Step by Step Checklist
1. Determine film type
Colour Transparency (slide)
- E6 process:
* ideal for magazine, book and
card reproduction
* most accurate colour for documentation
purposes
* make slides for presentations
or grant applications
Colour Negative (print) -
C41 process:
* personal record of your work
for the album
* make small print-runs using
mini-lab prints
* easiest to get a result
though difficult to get exact colour / density
Black & White:
* where final reproduction is
in B&W
* or where work is essentially
tonal in nature
* expensive unless youre
printing it yourself
2. Determine lighting
method
Natural light (simplest and
cheapest, but often inconsistent):
* direct sunlight
* diffuse sunlight
* light tent for
3D objects
Flash light (quick and accurate
colour possible with normal film):
* On-camera flash for quick
and easy results and shadows
* Off-camera flash to minimise
reflections
* Professional flash units with
umbrellas or a softbox for 3D work
Tungsten light (requires tungsten
balanced film or 80A filter over camera lens):
* A couple of halogen security
lights for doing it on the cheap
* A matching pair of professional
tungsten lights for accurate colour
3. Choose your film
FujiChrome Velvia - Most vivid
colours possible, quite warm 50 ISO
FujiChrome Provia - Still very
saturated but a little more real 100 ISO
FujiChrome 64T - Tungsten balanced
and quite neutral 64 ISO
Kodak Ektachrome - Neutral,
general purpose film (yawn) 100 ISO
KodaChrome 64 - Neutral colour
but takes ages to process 64 ISO
Kodak Ektachrome 64T - Tungsten
balanced like Fuji 64T 64 ISO
AgfaChrome 100 - Very neutral,
even a little cold colour 100 ISO
For B&W work try AgfaPan
25 for finest results (definitely on a tripod).
General rule - test your film
with appropriate lighting conditions before doing anything
important or unrepeatable.
4. Set up your lighting
For 2D work, placing two lights,
each 45 degrees to the work is a good starting point. This
minimises unevenness in illumination and cancels out shadows
by filling them with an equal amount of light from the opposite
direction. Test the evenness of light with a pencil, observing
the darkness of each shadow falling onto the surface.
For work under glass or with
a glossy texture (eg. oil paint), you may need to move the
lights even further out and minimise the light falling on
the photographer, camera, tripod etc... Remember to check
the evenness of exposure both visually and with the lightmeter.
Use of umbrellas can help, as can bouncing the light of a
white roof or wall.
For work in a deep frame, the
lights might need to be moved to minimise the shadow caused
by the edge. This is always a compromise between reflection,
evenness of illumination and the inevitable shadow intruding
into the work. Adjust to taste.
For 3D work, you can either
go for the safe option and light the subject evenly
and softly using a reflector on the light (eg. umbrella) or
a diffuser (eg. softbox / bounce-light) or use the light as
a vehicle to accentuate the interesting nature of the subject,
bringing out texture and form thereby creating another work
of art in the photography itself. This works best with B&W,
though can be used with colour film provided the contrast
of the subject it kept down using reflectors or additional
lights.
If lighting is unavailable,
try to work outside on an overcast day (sunny blue skies can
cause a nasty blue cast in your photos particularly if theyre
shot in the shadow of a building). Keep an eye on surface
reflections and in the case of 3D work, shadows filling them
using a reflector where necessary.
For small 3D works (especially
highly reflective ones such as jewellery), a small light tent
can be constructed using a white sheet over a frame, inside
which the work is placed on a platform and photographed in
just about any light with superb results!
5. Choose your lens
Normal (50mm) to short telephoto
(85mm - 100mm) lenses are best for 2D works as they minimise
the distortion caused by wide angle lenses and allow reasonable
working distances to minimise reflections and shadows of the
photographer.
For small 3D works a normal
lens is generally ideal (especially with macro capability).
Slight wide angle (35mm) lenses can give an interesting perspective
and additional depth of field to improve sharpness while short
telephoto (85mm) lenses allow the photographer to accentuate
a small section to make a point about the work.
6. Determine exposure
* For 2D work, use grey card
and set camera to f8 or f11. Under and over expose from the
initial reading to ensure at least one ideal frame.
* For 3D work either use grey
card or meter directly off subject and set lens to f22 for
maximum depth of field.
Again, do several exposures
to ensure one accurate frame.
