Volumetric Dust?

[Adept]

Hi! I have a forest floor scene, in which I am having the sun light shine through the leaves of a tree behind the scene to make the shadows/lighting more interesting. It looks good and all, but I want to try to add some volumetrics, but make it look like dust/micro particles floating through the air, making the rays shining through the leaves visible, rather than a more dense, thick fog obscuring objects behind it.
I'm going for something similar to this :

Except since it is more of a macro shot I want dust particles to be visible. How would I do this? Thanks
