The 3D revolution has once again struck the television and movie industry. More than two decades ago, studios attempted to cash in on the new technology that had been developed to show movies in 3D and while many of those efforts may appear laughable by today’s standards, they set a precedent and learned something through the trial and error period that has helped 3D technology move closer to main stream television viewing.
Conflicting reports on 3DTVs
For anyone who has spent any amount of time looking into 3D televisions, reading reviews, and basically getting their feet wet in the experience, they have undoubtedly heard a number of conflicting reports. There are some glowing reviews of 3D TVs that will make one want to run out to the store and purchase one today and there are also scathing reviews that lead others to believe that even though technology has advanced significantly through the years, it hasn’t been kind to 3D technology.
One of the major influences of the quality of 3D TVs is not necessarily that of the manufacturer, but of the programs that are being shown on 3D television. It doesn’t matter how much a person spends on a 3D TV if the television programs are movies that they are watching were filmed in two-dimensions. 3D televisions are designed to only capitalize on their advanced technology when receiving 3D signals. In other words, a 3D TV will certainly play 2D programs, but too many people seem to expect that those 2D programs will be enhanced in some manner by the television itself.
3D programs on the move
In order to get the most out of a 3D TV, there has to be a 3D signal coming in and many cable and satellite providers are still working toward providing that kind of option to their customers. Not every person will have access to 3D channels yet, and even those that do have access will likely not have many options.
The reason for the latter point is that not many television programs are being filmed in 3D yet, though that is changing every year and the number of programs delving into this technological advancement is increasing. Yet even with the television programs that are filming in 3D at the moment, not all of them are taking full advantage of its benefits and not all of them are going to look quite as powerful as a viewer might expect once he or she unpacks that brand new 3D TV and connects it in their living room. There are a few basic reasons for this and a few things that filmmakers should keep in mind when planning on filming in 3D.
3D technology is based on the human perspective
Most people can see in three dimensions because of the symbiotic relationship of two eyes. By being able to have two images from two perspectives, even though they are close together, the composite image formed in the brain creates depth, which is the cornerstone of three dimensional viewing.
If you were to think about depth perception, looking deep into the distance does not offer the same level of depth perception as do images that are closer to the eye. The same holds true with 3D filming and playback. Programs that have the two symbiotic cameras in close proximity to the action will show 3D images much more clearly than films that are farther away from the actual action.
In other words, the 3D perspective, or illusion, is lost the farther away a camera is from its action, characters, or target. In order to take full advantage of 3D technology, filmmakers using 3D cameras should consider filming closer to the action and when they do, the programs they create, when played on 3D televisions, will have a greater impact on the viewer and be closer to the ultimate 3D experience people expect.
