Change Gamma Value
You can correct the gamma by changing the gamma value. In other
words, the colour values (or grey values) between 0 (black) and 1 (white)
can be increased or lowered to achieve an optimal presentation. With the
help of the gamma correction, you can influence, for example:
 How pronounced the vessels in the sclera are shown.
 How bright the areas outside of the slit illumination are shown.
 How intensive the colour saturation of the image is.

Change the gamma value with the slide control (4).
☞

If the gamma value is too high, image noise can occur in the dark
areas.

once ideal settings have been established, they can be recalled at any
time.
