To get the best results in my 3D pictures, I designed and developed what I think is the best and most versatile bracket that may be found on the market today. I may be able to build one for you too in the near future.
But to fully understand how to design and build it, avoiding the other companies mistakes, it has been important to fully understand how 3D "works / needs to be done" to get the best pictures.
We see in 3D because of the separation of our eyes, and a global cultural process that from birth has told us what is close and what far, and how much far away. This skill we have achieved through a trial/error process when we were kids, and through observation while growing up.
Moreover: the average distance of the person's eyes is 63mm. A little more or less makes no difference. Because the brain will compensate and enhance the information it will receive.
As a consequence, to make the best 3D pictures (hey, I'm giving my tricks away!) we have to exaggerate this information, to give the brain a stronger 3D impression, but not too much, or it won't be able to resolve the image. Too much confusion: no 3D effect and little clarity of the image itself!
The Delpiano 3D Bracket, in its final version now, has a 110mm minimum separation (that is the average small camera's size nowadays), and a maximum separation of 310mm, which well fits the bill of getting a strong 3D effect in almost all situations.
This setup provides excellent results from 1m (3') up to 50-100m (150-300') that is more or less the kind of situations in which we may want to operate. Beyond those 100m, it's basically guesswork and huge separation, no 3D sunsets, sorry.
As an example, the pictures I have taken from the airplane may possibly have a separation of 300-500m (900-1500') from one shot to the other, guesswork and several attempts.
Anyways, check out my pictures on these pages and start evaluating the possibilities ...
