Sample Images taken with the
Cyclopital3D Stereo Base Extender
Shown in X-eye/Cross-eye Viewing Format
The sample images below show the change in scale in the Z dimension that results from using the Cyclopital3D Stereo Base Extender.
Note that two of the images taken with the SBE have “excessive” deviation (>4%). I personally like images with a lot of depth and experience no “discomfort” with such images, but others see the world (or in this case pictures) differently. Excessive deviation can be avoided either by moving back from the subject (closest object) a bit, or by framing to limit the distance to the furthest object in the background.

With SBE Total Deviation of 3.3%
Without SBE Total Deviation of 1.4%
With SBE Total Deviation of 4.5%
Note: These sample images were taken with the JVC GS-TD1 camcorder, however because the stereo base of the Sony is nearly the same as the JVC, the results are essentially the same for both the JVC and Sony. We also chose to use the JVC because the Sony won't capture still image and the JVC does.
The pictures were processed taking care to balance any differences in frame, scale, brightness, color etc., but because they were taken at slightly different times there remain small differences in these parameters that are not a result of the use of the Stereo Base Extender.
The caption of each image indicates the total deviation as a percentage of the image width. A commonly considered “optimum” deviation is 3%, if it's less, the image may have “little depth,” more and the image may become difficult (for some) to view as a result of "excessive deviation." There is a large range of opinion on the subject of deviation, probably because there is a large range in the way different people actually perceive stereoscopic imagery.
