Conventional photography is a portrayal of a 3 dimensional (3D) world in 2 dimension (2D). One technique that we can use to portray a sense of 3D in photos is to use shallow depth of field with large aperture lenses. The shallow depth of field can give us an apparent sense of depth and 3D. However, it gives us even more than that, it can give us a soft and dreamy bokeh that one will not see in real life.
The following photos were taken at Nakanoshima Rose Garden in Osaka. They were taken with Canon EOS 5D Mark II with Canon EF 135mm f/2L USM at f/2 and Canon EF 16-35mm f/2.8L II USM at 35mm f/2.8(the first shot).
