I guess my favourite thing about these angels and their AFAIK predecessors Orbs is the democratic nature of the mystical experience - with evidence! - afforded to those with a camera and without a brain.
UFOs, cryptozoological stuff, ghosts...all these need quite a bit of luck/preparation before you can get all wide-eyed and corner passers-by with drooling raving about this and that. Orbs and other focus-related stupidity are available to all, so the usual fakers of such nonsense can be bypassed by the small-timers.
In future, I will only accept my paranormal phenomena from mom & pop operations.
