High dynamic range mode
(MARLIN F-131B/C only)
The CMOS sensor of the MARLIN F-131 offers a special mode by which various
nonlinearity points, the so-called knee points, can be freely adjusted. This
enables the high dynamic range of the sensor to be compressed into 8 bit,
preserving interesting details of the image. This mode is also known as mul-
tiple slope (dual slope).
