Polaroid MicroCam - Manual (Page 9)

Operation
1 Place the specimen on the microscope
focusing stage, and focus and frame the
image.
2 Adjust the microscope illumination for
photography; Koehler illumination is
recommended for compound
microscopes. If you are using neutral
density filters over the light source when
viewing, remove them before taking
pictures. Check that the light is turned up
to the brightest setting, often called
“photo” or “overvoltage.” (This setting is
not suitable for viewing; overuse will
shorten the bulb life.)
3 Attach the camera to the microscope and
look through the camera viewfinder.
Observe the crosshair in the center of the
viewfinder while using the microscope
focusing knobs to refocus the specimen if
necessary.
Note: If you wear glasses to correct for
distance, you should wear them when
using the microscope camera.
4 Check the camera control settings and
adjust as needed.
5 Press the shutter button (11). The display
will show the exposure time for a few
seconds, then the camera will begin the
exposure. (The display will “count-down”
during the exposure).
6 After the exposure is complete the
camera will eject the developing picture.
Handle the picture by its wide border. Do
not bend or squeeze the picture while it
develops, and never cut pictures or take
them apart. See
Caution.
Allow pictures to develop for 4-5
minutes before judging the exposure or
color balance.
If the camera is unused for more than 15
minutes it turns off automatically.
Lighten/darken control (15)
A picture that is too light is overexposed;
use a shorter exposure time. If the
camera is set for
Automatic mode, press
the Darken arrow ▼ to decrease the
exposure time.
If a picture is too dark, it is
underexposed; use a longer exposure
time. Press the Lighten arrow
∆ to
increase the time.
The picture series (16) shows a normal
exposure (x1.0), and the results of
adjusting the exposure time by a factor of
x4.0, x2.0, x.50 and x.25.
