 image parallax | the apparent shift in relative positions of objects when viewed (photographed) from different vantage points |
| stereoscopy | the science of preceicing depth with two eyes |
| nearer | the ______ the object, the greater the parallictic angle where the optical axes of the eyes converge |
| farther | the ______ the object, the smaller the angle |
| depth perception | our brain compares parallictic angles of objects to determine relative location |
| stereoscopic overlap | 60 % of photo |
| stereoscopic parallax | the change in postion of an object form one photo to the next relative to the background |
| parallax of points | 1. related to the elevation of the point 2. greater for higher points than lower points |
