The Kula Deeper is a lens attachment designed to create stereoscopic 3D photos or video in-camera, with any camera. Constructed using four mirrors, the Deeper enables recording of stereo pairs within the same frame, which can then be viewed in 3D in a variety of ways. The free Kulacode software can be used to process recorded photos and videos into a range of formats for viewing, including the MPO format for use with 3D televisions, as well as anaglyph and stereo pair photo types.
The Deeper features an ABS plastic housing which can be mounted directly over a lens with 77mm front filter threads. Separately available step-up rings may be used for attaching to lenses with a smaller filter mount diameter. It is recommended to use the Deeper with a zoom lens with an approximate wide-angle position of at least 27mm.
Accurate exposure metering and autofocus control is maintained during use. However if autofocus becomes slow or inaccurate, it can be solved by simply focusing on one side of the image, which will then ensure both sides of the stereo pair are in sharp focus.
