This adjustment is needed when the camera is used for the first
time, after being unused for a long time, or when the ambient tem-
perature changes significantly (i.e. seasonal changes).
Note After adjusting the black balance, re-adjustment is not needed under the
same conditions.

performed in the field, unless it is necessary to change the lens.

at least 6.6 ft (2 m).
