machine. Once you feel the machine take hold of the material, release
the material and let the machine process it.
d. Mount the Viewgraph. If you did not use preframed film, you
would mount the viewgraph using the same process used to mount
viewgraphs produced using the diazo method.
As an illustrator, you also design transparencies in the 35mm slide
format. Like viewgraphs, the 35mm slide format also uses a 2 to 3
height to width ratio.
a. Advantages. This format has many advantages, the greatest one
being its size. Since a slide only measures 2 1/4 by 2 1/4 inches, you
can store and transport them easily. 35mm slides also adapt to a wide
variety of visual effects, such as color, 3D, and dropshading, to
mention a few.
b. Disadvantages. The 35mm slide format also has its
disadvantages. After considering the time required to produce the
artwork, photograph the artwork, and mount the slides, the most critical
is the production time. Additionally, it is often difficult and time
consuming to make corrections. Sometimes it is necessary to redo the
entire graphic; therefore, you must have an exact editing of the slide
by quality control or editing personnel.
c. Production Guidelines. The photo lab uses direct photography to
produce 35mm slides. Because of the production process there is a
simple realism you must keep in mind when developing slides: "What you
see is what you get." If you keep the realism and following guidelines
in mind when developing the slides, you can produce a quality finished
(1) Use the correct ratio. The 35mm slide format uses a 2 to 3
ratio. Always create the graphics with a 2 to 3 ratio in mind.
(2) Consult the photo lab. They can provide advice relating to
any system limitations, different lighting effects, which colors
photograph true, etc.
(3) Register overlays correctly. When using overlays to produce
the finished slides, ensure you use the required registration marks.
(We discuss overlays later in the lesson.)
(4) Allow adequate bleed area. Allow a sufficient amount of bleed
area around the image aperture for variances in camera alignment and
slide mounting. When developing graphics for the 35mm format, determine
the aperture area and draw it on
