The Cyclopital3D TD300 Stereo Base Extender is perfect for maintaining accurate depth portrayal when subjects are more distant from the camera. The camera allows you to zoom for adjusting the scale of "X" and "Y" and now, with the SBE, you can also change the scale in the "Z" dimension to increase the depth portrayed in the images you capture.
The Stereo Base Extender uses perfectly aligned high quality front surface mirrors to effectively increase the stereo base from 45mm to 180mm. This lengthening of the stereo base allows you to get 4X further away from your subject while still maintaining an optimal level of parallax. This SBE is only needed for subjects farther than about 4m from the camera. It is important to remember that your subject should generally be the closest object in the scene. When using the SBE, objects in the foreground closer than 4m could cause excessive deviation and make the image uncomfortable to view 3D, depending on the background.
