Setting the white balance
White balance is the process of correcting color bias due to light source variations, and adjusting white color so that
whiteness of objects appears correctly in the photograph. With the DS-L4, you can set the white balance manually when a
color camera is connected.
Adjusting the white balance when observing by a microscope
When using diascopic illumination for microphotography, adjust the white balance while you are photographing
a transparent part of the preparation.
When episcopic illumination for microphotography is used or a camera lens (instead of a microscope) is
attached to the camera, adjust the white balance using a white object.
For fluorescent photographing, we recommend that white balance be adjusted under normal light conditions
before photographing. If the screen is excessively dark or bright, adjust the iris diaphragm or brightness of the
light source, or use an ND filter to obtain the appropriate white balance.

Prepare an evenly white object, such as a sheet of paper,
and adjust the camera head position so that the object
covers the entire view of the DS camera.
Configure the illumination for observation or capturing.

Setting white balance
Settings at the power-on time
The white balance setting is saved when the power is turned off. It is resumed the next time the power is turned
on. However, if a custom setting ([SETTINGS] > [DS SETUP] > [MAIN] > [CUSTOM No.]) is selected, the white
balance specified in that custom setting is used.
White balance measurement area
The metering area that is currently set is also used to measure the white balance.
For details about setting the metering area, refer to "8.2.1 (3) Switching the metering mode".
Failure in white balance adjustment
White balance adjustment may fail if the object used for adjustment is not evenly white.
In such cases, a confirmation message appears, and you must adjust white balance again following the above
procedure.

Set an evenly white
object so that it
