These particles are actually floating spirits around us...they are not suppose to be seen unless you use a xenon camera flash that is strong enough to capture the floating spirits...they are all around us...try to take some photos in a garden which are quite dull and dark...you can sometimes see moving colour objects that floats in front of your camera lense...
But try not to take too much of these photos with human around...you may get sick...fever....etc...
In Malaysia, I have managed to get many of these photos, if by chance you are in Malaysia, do let me know...my e-mail address is kerrygoh18(at)yahoo.com.
