In artificial light conditions it is recomended to examine
the lighting conditions.
The exposure time of a standard camera corresponds
with twice the lighting period.
The exposure time of a Triple Scan high speed
camera is a third of the exposure time of a standard
camera.
Although the Licht is alternating each field has the
same video level.
The alternating light amplitude causes different video
levels for the three fields. This effect is only visible
during slow motion replay. The field flickering will not
appear in the Normal Scan output. The LDK 23HS
mkII uses various preset settings to accommodate
various artificial lighting conditions.
