There are many ways to blur a photograph; intentionally and by an 'oopsie-daisy'!  (Sometimes the oopsie-daisies turn into happy accidents!) You can blur your photographs intentionally by lens zooming or by using intentional camera motion.  You may be lucky enough to own a Lensbaby which adds a lovely blur to every photograph. For me, the easiest way to blur a photo is to use a low f-stop (f 1.4, f 2.8, f/4) to create a shallow depth of field, then focus on a single object and let the blur occur all by itself to the background. Remember it is WHITE week, so if you can blur something in white it’s a bonus!
