2. what are the differences between your two-dimensional photograph and the three-dimensional scene that you photographed?

Answer

In the 2D photograph objects have only height and width with no depth. The objects in the photograph are flat too. The objects in the 3 D scene have height, width and depth.

Explanation

The objects in the 2D photograph appear to only have height and width. In the real world scene (3D), the objects captured have a depth. In order to achieve a 3D scene using a 2D object, one should introduce a linear perspective to make all the 2D objects appear 3-dimensional.
