How to get quality images using the software
Override the default white balance by following the steps below:
• Hold a white sheet of paper in front of the slit lamp
• Swivel in the diffuser for a homogeneous illumination
• Reduce illumination to a minimum (the test paper should appear grey on the screen)
• Make sure there is no glare
• Click the White balance button (each profile requires a separate white balance)
Image quality –
Best: lower resolution, but higher frame rate
Automatic adaption of gain and exposure time –
Increase illumination
on SL (may cause noise)
Exposure time –
Dependent upon the movement of patient and SL; low
exposure time for videos and moving patients
Gain –
Electronic amplification of the signal. The darker the output signal,
the higher the basic noise. Keep Gain as low as possible. Instead, increase
illumination at the SL.
Gamma –
Changes black/white appearance without changing color
temperature (keep at 100%)
Fine setting –
Color information; 100% = maximum color information,
0% = black/white image
Coarse setting saturation –
Leave at 0% for the most natural impression.
Higher value will amplify the given color information.
