Tried the new shallow focus photo mode today.  Spark bobs up and down while taking the picture.  On the SD card there is a new folder called SHALLOWFOCUS containing numbered folders each of which have 16 images in it.  The first one is at 1440x1080 resolution and the other 15 are at 720x540 resolution.  There doesn't seem to be any "focus" effects on any of the images.
Do these images require additional processing?  If so how?
DJI please post an example of a SHALLOW FOCUS picture.

Answer to my question:  Download photos from Spark to your phone and process in the GO4 app.
