This is the Rosa Rugosa bush (flowers not present in this photo) and the red bud you see are rose hips. Bokeh is a photographic term for the desired quality of the blurred section of a photograph (the highlighted out of focus circles)
Here are four completely different examples of various lighting and depth of field that I just love to play with!
This was taken at a small B&B/Farm in Maine. The lighting in the barn was just perfect to capture this little one! Only a face a mother could love?
