What we are talking about is a subtle effect, no-where near as strong as true 3-D images. For those posters who maintain that there is no 3D-like effect....if you can't see the effect, there is no point in arguing whether it exist or not.

Yes, there is no point of arguing about something that cannot be defined. Unless and until it's defined it remains just a figment of one's imagination.

Any image on a two dimension surface - screen or print is two dimensional. However, since people started putting paint on canvas, artist have developed methods to give the perception of depth or a third dimension. However, at the end of the day it doesn't exist it is an illusion.

There are some standard tricks that work for both painting and photography.


The graphic artist M. C. Escher was a master at producing art work with an amazing illusion of depth.


In one of his pieces - water ran up hill.  It was the only way it could get form point A to B.  Depth is a matter of fooling the brain.  No camera is any better at that than any other.  I much say that every image I have seen with the SD or DP that was claimed to be "3-D" appeared so because it (maybe accidentally) the photographer used some of the well established methods of creating the illusion of depth.
