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
An awesome detail on an iron fence! Check the detail! The Photo by Michal Dzierza, taken in Bloomsbury, London. Although not mentioned by the photographer, I strongly uspect that said cast iron gates relate to the British Museum.
Depth of field can emphasize portions of the photograph. Shallow depth of field also creates isolation of your subject and eliminates structure in backgrounds.Depth of field can set the mood of a photograph creating a soft luxurious look.
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.
