Description
The Fast Focus Tutorials are mini-manuals, dedicated to a specific aspect of 3D (stereo) photography. The tutorials are available only as downloadable PDF files. This serves the dual purpose of keeping them very affordable while minimizing their impact on the environment.
PDF ebooks work GREAT in both Kindle and NOOK readers, as well as in your tablet or computer.

Stereo base is a subject of much needless disagreement and concern. In the final analysis the correct base for any scene is simply the one that yields the most comfortable to view stereos for either you or your average target audience.
There are numerous factors involved in establishing the correct stereo base for a particular situation, many of which are affected by the presentation format, the viewing method, and even the physiognomy and preferences of the persons doing the viewing. Many of these factors are beyond your control.
In this easy to follow explanation, all the factors of stereo base calculation are described. Then, a keep-it-simple-stupid method is provided that you can use to get “close enough” with ease in 99 out of 100 situations. As in horseshoes and grenades, close enough can work just fine for the stereo base.
Regardless, it is often hard to get close enough. For that reason it is important that all stereographers understand what happens in various scenes and why the stereo base sometimes has to be reduced by 50% or even doubled. Guess wrong and the base can be off by as much as a factor of 4 times, resulting in either flat looking stereos or, worse, stereos that are difficult or impossible to fuse.
Take away the stress and learn the easy ways to select your stereo base, plus the reasons why your stereo base sometimes “seems right”, but is disastrous in the finished stereo. How to “Keep it Simple.” This is a smart buy.
