From 

Exam 

(see Figure 30): 

  one can set a delay in seconds (default 0) between subsequent snapshots; 

   A separate delay can be set between stereo pairs; 

  Additionally the fixation target can be set to be permanent or blinking at 3 different speeds 

(slow, medium and fast); 

  The chin rest can be set to automatically adjust its position by clicking on ENABLE. 

  HIGH UNIFORMITY Image Processing Strategy 

 

HIGH UNIFORMITY Image Processing Strategy. 

It is possible to select between two different Image Processing Strategy: Uniformity and Contrast. 

This setting affects the internal gains and color tunings of the Camera. The final retina image has 
different color balance and luminosity, but the original image details are the same. 

One Strategy is not better than other and mostly depends on personal taste and habit. 

UNIFORMITY  strategy  -  with  this  selection  the  image  appears  very  uniform  in  color,  with  mild 
shades. Micro aneurisms and macula details may appear more visible with this setting 

CONTRAST  strategy  -  this  selection  returns  an  image  with  more  contrast  and  luminosity 
difference.  Details  may  appear  more  evident  but  image  has  a  more  grainy  aspect,  especially  at 
high zoom levels.
