A how-to on stereoscopic media creation

A primer on stereopsis
Stereopsis refers to the ability to perceive depth, stemming specifically from the disparity and integration of visual information from two laterally located eyes. Each eye receives a slightly different angle on objects in the field-of-view, causing horizontal or binocular disparities, which when integrated together, produce an understanding of environmental depth to supplement other visual factors such as motion parallax, contrast, overlap, and more. In anatomy education, spatial awareness and understanding of the distances and relationships between structures is paramount.
Creating stereoscopic 3D anatomy learning experiences: an artistic and technical reference
The following document characterizes methods and considerations, both artistic and technical, when creating a stereoscopic-3D anatomy learning experience. However, it is generally also suited to any type of close-subject stereoscopic media. All software used and referenced within is free and/or open-source, with the exception of some proprietary color-correction programs (which are fully optional).
An .stl model mount for dual-smartphone stereo filming setup
In an effort to not only democratize the distribution of stereoscopic anatomy learning experiences, but also their production, we have developed a 3D-printable, standard-tripod mountable stand that takes two smartphones (not necessarily of the same model) and positions them with adjustable inter-camera distance to film a subject.
Spaces are included for wired phone setups (so that the phones can be controlled from an external computer connection). More details on such a setup are included in the attached whitepaper pdf file.
