Here is a great video about how to preserve the 3D look when your camera reduces your image to 2D. Depth of field or lack of it, light direction, contrast, colour, perspective, haze, fog, are all our friends.
Sometimes conventional shooting, and by the book processing, works against 3D and diminishes the image.
The presenter uses the word "landscape" but it applies to other subjects as well.
