3D stereopticon Photographs of Rosicrucian Park - San Jose

     During our last trip to San Jose we visited Rosicrucian Park and I took along my new 3D camera and found the Park had many good subjects to choose from.
    With stereo photography you get the best 3D effect by having a strong foreground subject with a farther away background thus emphasizing the distance between them when viewed as stereo.  The earliest stereo viewers came from the Victorian era where they were commonly found in the home's parlor and used for family entertainment.  Later in the 1950's there was the View Master 3D viewer that viewed a series of images custom mounted on a wheel shaped slide.

     Our two eyes see stereo images naturally by having our brain combine the two separate images and making sense of them by creating a perception of depth.  Traditional camera use only one len and record the image the same as you would see it with one eye closed.
     Stereo camera have two lenses spaced about 4" apart, the same as our eyes. The two images are exposed on the same frame of film resulting in a left and right image that appears as one image when view with a stereo viewer of using freeviewing techniques.

     Freeviewing is a way to view stereo images on a computer monitor. The aim here is to overlay the left and right image by directing the eyes. As stereocards always have the left view on the left, and the right view on the right, 'parallel' viewing is appropriate, with each eye looking at the view in front of it. The eyes are therefore directed as if they are looking at an object in the far distance, but the image is not at a great distance, so the eyes need to focus more closely than normal for that convergence.



normal
Normal Viewing
 both eyes fixate (converged on) the same point. The fields of view of the two eyes overlap.






parallel
Parallel Stereoscopic Freeviewing :
Eyes pointed as if looking into the distance. They fixate similar points on the left and right views presented to them, which then fuse into a single 3D perception.

This is a representation of what you see when successfully freeviewing. The 3D percept is in the middle, flanked on either side by a ghostly image which is only seen in the left or right eye respectively. Try it on these images..

this shot has one of the best depth effects

another great 3D effect with the varying depths of tree branches becoming very apparent
