Summary
[edit]| Description |
English: Illustration of the limits of parallax. The line represents the Z axis, so imagine that it is laying flat and stretching into the distance. If the camera is at X point A on an object at 30 feet. Point B is on an object at 200 feet and point C is on the same object but 1 inch behind B. Point D is on an object 250 feet away. with a normal baseline point A is clearly in the foreground, with B,C, and D all at stereo infinity. With a one foot base line, which multiplies the parallax, there will be enough parallax to separate all four points, though the depth in the object containing B and C will still be subtle. If this object is the main subject, we may consider a baseline of 6'8 but then the object at A would need to be cropped out.
Now imagine that the camera is point Y, now the object at A is at 10,000 feet, the point B is on an object at 10,170 feet C is a point on the same object 1 inch behind B. Point D is an object at 10,220 feet. With a normal baseline, all four points are now at stereo infinity. With a 333 foot basline, the multiplied parallax allows us to see that all three objects are on different planes, yet points B and C, on the same object, appear to be on the same plane and all three objects appear flat. This is because there are discrete units of parallax, so at 10,230 feet the parallax between B and C is zero and zero multiplied by any number is still zero. |

{{vector version available|new image name}}.
It is recommended to name the SVG file “Parlimit.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
