Backyard Winter Nature in New Jersey — Spring is Coming!!!

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.

Winter Indoor Nature in New Jersey: Stink Bug Eating Pink Grapefruit.

The invasive stink bugs that invaded Pennsylvania have expanded into New Jersey. They come into houses during the winter to stay warm.  As seen here, one is feasting on a pink grapefruit that I just brought back from Florida.
