Every photographer has their personal preference of the "bokeh" effect in the background of their pictures. Some love the sparkly round blurred background such as shown in the dragonfly photos, some like the odd shaped bokeh often rendered by manual lenses and some prefer the perfectly creamy background where all the colors blend together into one smooth background. (usually my personal preference)
I think each has it's own unique character to add an extra element to create with.
I love the dragonfly photo, and couldn't decide which to post, so I posted all 4 versions. It was taken in very bright sunshine and was a tough challenge to expose for texture, etc.
I also love the shadow under the dragonfly-he looks like he's praying for his next meal.
Comments welcome and appreciated!
