Using the SunEye
Sky Type
Sky Type
The SunEye 210 automatically analyzes the skyline image and attempts to identify unobstructed
open sky and shade-causing obstructions. The image may contain many types of objects, includ-
ing:
• Open sky
• Clouds
• Sun
• Structures
• Trees
With a wide variety of possible colors, intensities, and textures, the analysis is difficult and com-
plex. For instance, differentiating between a bright white cloud and a white painted wall is one
of the difficulties you may encounter.
The SunEye 210 uses advanced image processing techniques and performs well in most condi-
tions. If occasionally the software fails to detect the open sky, you can manually edit the image.
If you are capturing many skylines, however, this editing operation may become time consum-
ing.
You can increase the accuracy of the detection by using a new feature that adjusts the SunEye
210’s color balance before capturing the skyline. This new control addresses two common types
of detection error:
• Confusing clouds with obstructions
• Accurately defining the edges of complex shading (such as vegetation)
The Skyline Detection control is available when viewing the Preview Mode. Access it by click-
ing the arrow in the upper left corner of the screen. The following pop out menu will appear:

The normal setting is the default and will work well for most conditions. However, in certain sky
conditions, you may see incorrect skyline detection such as below, where the sky is indicated to
be an obstruction. This is most typically seen in the case of bright white clouds and blue sky.
