All the above are taken with 50mm (100mm 35-Equiv) Olympus Zuiko, a legacy lens which fits my Micro 4/3 camera with an adaptor.  Shutter speeds between 1/500 and 1/1000, aperture f1.8.  With this lens wide open the plane of focus is very shallow, a few centimeters on objects which are a metre or two away.  Focussing is manual, aided by the magnification function available via the viewfinder.

The wide aperture has the effect of throwing the background right out of focus rendering it as just a blur in most cases and the same can happen to objects closer to.  These are my selection from contacts below.

Composing the out-of-focus parts isn’t easy; I think it is important to exclude any undefined highlight areas such as glimpses of bright sky especially where they occur at the edge of the frame. With this aesthetic code you always seem to end up shooting past or through, but it does direct attention to the centre of interest.
