This image was taken in a local hospital earlier today and demonstrates the effective use of a large lens aperture f1.4 to isolate the two subjects in the foreground from the out of focus background. The way a lens renders out of focus detail is referred to its ‘bokeh‘. If you look closely you will see that the large haggered looking subject on the right has one eye in focus while the other is out of focus. This shallow ‘depth of field’ is also associated with larger lens apertures.
According to the Keywords used in the image metadata the smaller and more attractive subject is a Sylvie Goldsmith while the the larger subject is of no interest to the viewer and quite rightly goes un-named. The larger subject would also benefit from some serious work in Photoshop.
In case you are worried the rough looking subject on the right will be teaching at Bath University as normal today.
