Adding mist/light fog/particles into the scene? (to create depth/specific look)

[Nathan Skillen]

Looking to create an effect similar to adding fog to a scene, but a lot less dense - more like a mist to create a summery look with lots of depth.

Would a household water mister work?

Also thinking of any other particles I could blow through the scene to create depth?

Shooting outdoors on moving vehicles (open-top bus & a ferry) so there will be natural wind.

Any ideas to help create this effect?

All location shoots, fairly low profile
