If you hover your mouse over the above left eye image the matched right eye image will be seen.

Historically, one of the issues with Stereoscopic 3-D capture is that subtle but unwanted differences between the two image can cause viewer problems as the eye thinks it's seeing one thing, while the brain believes it's seeing something else.

This is one of the biggest issues with 35mm film capture for stereoscopic 3-D as differences between the two images - left and right eye - can be just too variable, with differences in film movement through the camera mechanism; differences in film processing; differences in grain patterns; not to mention stability and variation issues with film projection.

There have been many attempts to overcome these issues, with developments such as dual-lens 70mm cameras shooting two 35mm frames simultaneously, overcoming the major issues of dual 35mm camera shooting, but at the expense of very specialised shooting systems.

Digital cinematography, combined with DI and digital projection, can far more easily overcome these issues with a number of additional benefits as well.

To see a bit more about how Stereoscopic 3-D works (and for a good laugh!), have a look at the video on the BBC website Technology Page (and which is on the previous 'Introduction' page).

As always, test before committing to a particular style of stereoscopic 3-D shooting.
