In photography, at times, foreground is often emphasised to give a sense of depth to the image. Such compositions also provide a two-dimensional image a three-dimensional feel. Another plus point of such photography is that the image engages the viewers to explore the scene or composition rather than just observe it.
There are a few tips that can enhance the feeling of depth in your shots. First, change the viewpoint or composition to transform your photo with about two-third of the composition becomes the foreground. Bring the camera close to the ground rather than shooting at eye level. This provides a better perspective as objects get smaller as they move into the distance, creating a greater sense of depth.
Secondly, try to include objects at varying distances from the camera to give a three-dimension look. Some objects of interest in the foreground lead the viewer's eye around the scene to the subject in the distance. It needs to be noted there is more depth to be found vertically than horizontally, so try to capture more of the scene vertically.
Thirdly, wherever possible, use some foreground objects to create a natural frame around the subject in your photograph. This also, enhances the sense of depth by guiding the viewer through the scene, allowing him or her to explore it.
Moreover, photographing with a wider angle or zooming out always exaggerates the perspective in a scene with a greater sense of depth. Also, at times, layering and overlapping of foreground objects can help viewers to reconstruct the three-dimensional scene in their minds.
