This is the grain on the wooden boardwalk in Jones Beach. It’s interesting to see that it is mostly straight lines and rarely curves. Inspecting the image, it would be difficult to tell what it was, and it is difficult to tell which color is the foreground and the background, which creates an ambiguous figure/ground relationship.

This is an obvious figure/ground relationship because it is obvious which is the background as it takes up the most volume in the image. Although it has an obvious figure/ground relationship, it is not obvious what the actual thing in the image is.

This is ambiguous because it is hard to tell which is in front and which is in the back due to the ratio of light to dark. There seems to be an even amount of each within the image.

This is obvious because it is obvious what the figure is. The contrast between the elements in this photo makes it obvious which is the figure. There are also shadows on the dark item, which makes it obvious it is on top of the ground.

This is an ambiguous figure/ground. It is hard to tell which is the figure because even though there is contrast, they take up about the same amount of space in the photo.

This photo of a leaf on the street is an example of an obvious figure/ground relationship. The shadows that the leaf is casting on the ground shows that it is on top of the street.
