After a heavy frost, even the most simple details can take on an extraordinary appearance. I made this photograph with a wide open aperture, and as close as possible to give a really narrow depth of field. This removes/blurs most of the finest details of the frost and dried grass blades, and concentrates the focus (no pun intended) of the image on the form, the sweep, of the grass. But, to me, the little bit of frost detail visible just along the narrow plane of focus, gives that extra little “spark” to the image.
