Image Acquisition
image in which you are interested, it is possible to influence the result of this
measurement by adjusting the weighting.
A setting of 120% means that 120% of the exposure time set in the display
window or measured by pressing the appropriate button is used for actual
acquisition.
A setting of 50% means that 50% of the exposure time set in the display
window or measured by pressing the appropriate button is used for actual
acquisition.
The setting range is between 5% to 120%.
EXAMPLE:
A thick sample is acquired in bright field. The empty image background is
much brighter than the darker sample. The measurement produced an
exposure time of 50 ms, at which the background would not be overexposed
during acquisition. Setting a correction factor of 120% extends the effective
exposure time to 60 ms, which ensures that the darker area of the sample is
exposed more brightly. The brightest area of the image, which is not of
interest, is overexposed here by 120%.

The software sets the exposure automatically for each individual shot when
the check box
Automatic
is activated. This makes it possible to generate
acquisitions with the correct exposure without having to enter manual
presettings. For each individual acquisition the correct exposure time is
calculated and set in advance.
If the
Auto Live
check box is activated, the software continuously sets the
exposure during the live image. In this way it is possible to generate images
with the correct exposure without having to enter manual presettings. The
exposure time currently calculated in the live image is used for each individual
image.
