18 Leica DFC Cameras – Image Acquisition Guide
Please note that auto-exposure is not suitable for faint
images and is limited to 1 sec.
Manual
Automatic exposure offers the best overall image
quality for most acquisition purposes. However, in
situations with difficult light conditions, you may wish to
adjust the exposure.
Exposure time is applied non-linearly and, depending on
the camera model, it is displayed in microseconds,
milliseconds or seconds.
Gain
Increasing Gain is a way of making an image brighter
without increasing the exposure or where the amount of
light is low. However there may be a degradation of
quality at high gain values because there is a greater
noise content.
When Automatic Exposure is active Gain is disabled.
The default value is 1.0x.
IC 3D camera only
The gain for the IC 3D sensors can be controlled
independently or locked together. The default is locked
together but this can be changed in the hidden menu in:
Extra>>Separate Gain Values.
Color Saturation (Color cameras)
When viewing a sample through an eyepiece and
comparing it with the overall color of a live or captured
image, you may find that the intensity of color of the
image requires some adjustment.
The color saturation of a whole colored image may be
increased or decreased from the norm using the
Color

slider.
To adjust towards more artificially vibrant colors move
the slider to the right. The maximum value is 3.00x. This
is useful when the image may be dull or when
