2.5D, 3/4 perspective and pseudo-3D technologies are graphical projections which cause a series of images to appear to be three-dimensional (3D) when in fact they are not.
Now you can make a 2.5D photo based on your own picture. “2.5D Photo” uses a proprietary algorithm and is able to make any picture “pop” by increasing its visual depth. The enhanced photo will look very vivid and interesting.
