Early Blooming Purple Crocuses.

The Purple Crocuses have started blooming across the street. This is a good sign that spring is coming. In order to get a deeper depth of field (DOF) I took several images each with slightly different focus points, and then combined the images using Helicon Focus get the composite image. The focus range was just around the flowers, keeping the background leaves out of focus.
