Apparently you've misunderstood either 3D (or more accurately stereoscopic) vision, depth of field, or both. Cue detailed HN-worthy explanation of each... but frankly, you'd be better off perusing the myriad of resources available on these two subjects.
- grandalf 10y agoPlease explain. My point is that stereoscopic vision lets our brains ignore more information by identifying the depth of interest and ignoring the rest. Similarly, trying to identify the direction of a sound using only one ear is very difficult, and there is inferior signal to noise ratio available to our perceptual system. The same applies to stereoscopic vision.
