In general, the procedure for photomicrography

is the same as usual. This section describes special considerations

that apply when taking photographs

with the dual-viewing

attachment

CX-DO mounted.

1. Using the trinocular observation tube mounted on top of the microscope,

you can take photographs that include the

pointer.

0 When you use Olympus trinocular observation tubes, photo eyepieces, and photomicrographic

equipment, the pointer

arrow is always focused on the film plane.

2. The brightness

of the pointer is set to be brighter than the specimen

to ensure adequate

contrast. This has the

following

effects on photographs that are not apparent during visual observation.

@ Since the pointer is always overexposed

when exposure is correct for the specimen, the pointer color will bleach to

white in color photographs.

@When

taking photographs with photomicrographic

equipment

with automatic exposure control, the brightness of the

pointer will cause the specimen

to be underexposed.

In such cases, set the photomicrographic

equipment's

compensation

to the OVER position in accordance with the specimen

distribution.

@ Since the effect of the pointer is particularly noticeable when making long exposures

of dark specimens, check the

exposure time with the pointer illumination turned off, then make the exposure

manually after turning the pointer

illumination on again.

3. Photomicrography

is performed at the main observer's

position.
