3. Go to the Fisheye tab to select the following parameters:
 Camera's orientation - type of de-warping algorithms based on orientation.
 Calibration - to avoid de-warping artifacts, it is important to position the calibration circle within the Camera's
view as accurately as possible. First, try Auto Calibration, then manually adjust the viewing range (if needed):
 Use scrollers to move the circle horizontally or vertically (or drag it with a mouse)
 Use the botton scroller to specify the shape of the lens (panamorph lens support)
 Use a mouse wheel to resize the circle
 Camera's view angle.
Note: It is recommended to keep Camera on Scene to monitor any image changes while adjusting settings.
4. Click Apply or OK when finished. To discard changes, click Cancel.
Once Camera is established as a fish-eye camera, de-warping can be performed. See "De-warping Fish-Eye Cameras"
for details.
