This is a good example of shallow depth of field because the background (The Eiffle Tower) is out of clear view and the small, miniture tower makes it look like the original tower is its shadow which works well with this shallow depth of field photograph.
Autumn tree: I like the angle of this shot because it enhances the trees large size. Additionally I like the shallow depth of field, focussing the lower leaf yet enhancing its colour with the out of focus background. SHALLOW DEPTH OF FIELD
Diagonal, leading lines, repetition:This is an example of maximum depth of field. The image was taken low enough to obtain all the bicycles as well as making sure they are all in focus, creating as if the bicycles never end.
