At our recent field trip to the MFA a few of us tried applying these principles to give you examples of Gestaltian Psych in action.
This is the most basic of visual shortcuts we use. When given an image we quickly determine what is the figure and what is the ground. Here Jess uses the stark silhouette of the skyline to create a figure on the background of the gray sky.
Here I kept the background blurry (bokeh) to highlight the figure from the ground. However I left enough detail since the background helped add context to the figure.
Here I purposely made it hard to distinguish figure from ground for anything but the fallowing or flying figure. However you wish to interpret the image. Sometimes you can purposely play with these principles to add interest to your composition.
